Statistical Analysis Programming Practices

Statistical Analysis Programming

With the growing demand and endless possibilities, statistical programming is more relevant than ever. From data FAIRness to stakeholder relationships, every aspect matters. Best practices in statistical computing mean quality assurance at every step[1].

So what are the common mistakes to avoid? What are the golden rules to follow? Stick around, and let’s find out together!

Arbitrary naming of variables

The Problem with Non-Descriptive Naming

When we choose arbitrary or non-descriptive names for variables, we’re setting ourselves up for confusion and difficulty later on. Imagine trying to figure out what m1 is supposed to mean when you come back to a project after a few weeks. It’s like trying to read someone’s mind!

Examples in R:

  1. Good: mean_treatment <- 5.6 explains itself. Bad: m1 <- 5.6 doesn’t tell us anything.
  2. Good: total_sales <- 1500 gives a clear picture. Bad: ts <- 1500 can be confusing.

How Proper Naming Conventions Enhance Readability for Statistical Analysis Programming

Proper naming conventions are like a helpful guide, pointing you in the right direction. They help you understand what a variable is for without having to trace back through the code.

Examples in Python:

  1. Good: average_age = 30 makes sense. Bad: aa = 30 might leave you scratching your head.
  2. Good: employee_count = 10 is descriptive. Bad: ec = 10 could mean anything.

Example of Good vs. Bad Naming

Having meaningful names can make your code a joy to read and maintain. Here’s how good and bad naming can look side by side:

Examples in R:

  1. Good: student_grades <- c(90, 80, 70) Bad: sg <- c(90, 80, 70)
  2. Good: temperature_record <- c(25, 30, 27) Bad: tr <- c(25, 30, 27)

Examples in Python:

  1. Good: price_list = [100, 200, 150] Bad: pl = [100, 200, 150]
  2. Good: current_weather = 'sunny' Bad: cw = 'sunny'
  3. Good: user_preferences = {'color': 'blue', 'size': 'medium'} Bad: up = {'color': 'blue', 'size': 'medium'}


Arbitrary naming of variables is like throwing a wrench into the gears of collaboration, maintainability, debugging, and documentation. It’s important to make code as readable as possible, so be mindful of naming conventions. After all, good naming is an art that can make coding a smooth and enjoyable experience!

By following proper naming conventions, we ensure that our code is understandable by everyone on the team, making our lives, and the lives of our fellow developers, a whole lot easier. Happy coding!

Using data types inefficiently

Issues with Using Numerical Types Instead of Factors

Sometimes, we might feel tempted to code categorical variables like treatment groups as numerical types. However, this approach can lead to misunderstandings and errors. In R, factors are designed to handle categorical levels like treatment and control, and using numerical types for this purpose can be like fitting a square peg in a round hole!

Examples in R:

  1. Wrong: treatment <- c(1, 2, 1, 2) where 1 and 2 represent treatment and control. Right: treatment <- factor(c("treatment", "control", "treatment", "control"))
  2. Wrong: gender <- c(0, 1) for male and female. Right: gender <- factor(c("male", "female"))

How R Can Efficiently Handle Categorical Levels

R has a neat solution for handling categorical levels: factors! Using factors in R can make our code more efficient and our data analysis more insightful. It’s like giving names to our categories instead of confusing numbers.

Examples in R:

  1. Efficient: day_of_week <- factor(c("Mon", "Tue", "Wed")) gives clear understanding. Inefficient: day_of_week <- c(1, 2, 3) can be ambiguous.
  2. Efficient: status <- factor(c("active", "inactive")) clearly defines the categories. Inefficient: status <- c(0, 1) lacks context.

Practical Examples

Here’s how coding categorical variables as numerical types might look, and how we can fix it:

Examples in Python:

  1. Wrong: grades = [0, 1, 1, 0] where 0 and 1 represent fail and pass. Right: grades = ['fail', 'pass', 'pass', 'fail']
  2. Wrong: cities = [1, 2, 3] for New York, Los Angeles, and Chicago. Right: cities = ['New York', 'Los Angeles', 'Chicago']
  3. Wrong: sizes = [0, 1, 2] for small, medium, and large. Right: sizes = ['small', 'medium', 'large']


The proper and efficient use of data types is not just a coding nicety; it’s a fundamental practice that has profound impacts on data quality, operational efficiency, and even the financial bottom line of organizations.

Consider the economic impact of these practices. Poor data quality costs organizations an alarming average of $12.9 million per year, according to Gartner’s estimation in 2021. IBM took it further by calculating the annual cost of data quality issues in the U.S., amounting to a jaw-dropping $3.1 trillion in 2016. These figures aren’t just abstract numbers; they translate to real lost sales opportunities, additional expenses, and potential regulatory fines.

The inefficiency in using data types, such as coding categorical variables as numerical ones, may seem trivial at first glance, but it contributes to a significant portion of these costs. Correcting such data errors and handling the resulting business problems can devour 15% to 25% of a company’s annual revenue on average. It’s like throwing money down the drain!

Writing messy code

We’ve all been there—tight deadlines, late nights, and the temptation to cut corners in our code. But messy code is like a stain on a favourite shirt: it sticks out and can cause all sorts of trouble. Let’s break down why we should avoid it and look at ways to keep our code clean and tidy.

Importance of White Space and Tabbing

White space and tabbing are like the breadcrumbs in coding. They guide us through the code, making it easier to follow and understand. Think of white space as a visual cue that helps you keep track of where you are. For example, consider the difference between these two Python code snippets:


def calculate_total(x,y):total=x+y;return total


def calculate_total(x, y):
    total = x + y
    return total

In R, it’s the same story: Messy:

calculateTotal <- function(x,y){total=x+y;return(total)}


calculateTotal <- function(x, y) {
  total = x + y

The clean versions are much easier to read, right?

Dangers of Duplicated Code

Repeating code is like telling the same joke over and over; it loses its impact. Not to mention, it’s harder to maintain. If a bug sneaks into that duplicated code, you’ll have to fix it in every single copy! Here’s a comparison in Python:


def multiply_numbers(x, y):
    return x * y

def multiply_values(a, b):
    return a * b


def multiply_numbers(x, y):
    return x * y

And in R:


multiplyNumbers <- function(x, y) { return(x * y) }
multiplyValues <- function(a, b) { return(a * b) }


multiplyNumbers <- function(x, y) {
  return(x * y)

Why repeat yourself when you can be more efficient?

Encouraging the Use of Functions

Functions are like the secret sauce in your coding recipe. They help you reuse code and make it modular, testable, and maintainable. Instead of writing the same code multiple times, you can write it once in a function and then call it as needed.

Python Example:

def greet(name):
    return f"Hello, {name}!"


R Example:

greet <- function(name) {
  paste("Hello,", name, "!")


See how neat and tidy that is?

Conclusion: Don’t Let Messy Code Mess Up Your Day

Writing messy code might seem like a minor issue, but the consequences can be far-reaching. It affects not just readability and maintainability, but can lead to serious business losses. From the Ariane 5 rocket explosion that cost nearly $8 billion to the 17.3 hours developers spend each week dealing with bad code, the impact is real and significant.

So next time you’re tempted to ignore those tabbing rules or duplicate some code, remember the bigger picture. Think about your colleagues, your future you, and even your company’s bottom line. Give your code the love and attention it deserves. After all, clean code is happy code, and happy code makes for happy developers. Let’s keep it clean, friends!

Hard Coding

Hard Coding: Taking the Easy Route?

Ah, hard coding—often a coder’s guilty secret. We’ve all done it at some point, right? But as tempting as it may be to plug in those numbers directly, it can lead to a tangled web of problems down the line. Let’s explore why and see what we can do instead.

Explanation of Hard Coding vs. Using Constants

Imagine you’re painting a mural, and instead of mixing colors from primary shades, you buy a new can for every hue you need. Sure, it works, but it’s neither efficient nor flexible. Hard coding is similar. It’s embedding specific values directly into the code, like radius = 10 in your program.

Now, consider using constants. They’re like your primary colors, defined once and used throughout the code. For example, RADIUS = 10. Suddenly, you have a standard that’s easy to manage and adjust. 🎨

Here’s a comparison in Python:

Hard Coding:

def calculate_area():
    return 3.14 * 10 * 10

Using Constants:

PI = 3.14

def calculate_area():
    return PI * RADIUS * RADIUS

And in R:

Hard Coding:

calculateArea <- function() {
  return(3.14 * 10 * 10)

Using Constants:

PI <- 3.14
RADIUS <- 10

calculateArea <- function() {
  return(PI * RADIUS * RADIUS)

See how clean and logical the constant approach is?

Why Constants are Preferred

So why are constants such a big deal? Let’s break it down:

  1. Flexibility: Constants allow you to make changes in one place, rather than hunting down every instance of a hard-coded value. Imagine changing the radius in hundreds of places versus just once!
  2. Maintainability: Constants make your code more readable, making it easier for you or your team to understand and maintain the code later on. Nobody likes digging through spaghetti code to find that one value.
  3. Reusability: By using constants, you make your code more reusable in other parts of your project or even in other projects. It’s like having a universal remote for all your devices.
  4. Scalability: Constants help your code grow gracefully. You can scale up without the headaches of tracking down hard-coded values.
  5. Security: If you hard code sensitive information, you’re leaving your secrets out in the open. Constants can help you manage those values securely.

Conclusion: Choose Wisely, Code Wisely

Hard coding might seem like a shortcut, but it’s a path brimming with obstacles. Lack of flexibility, reduced maintainability, limited reusability, and even security risks—it’s a minefield that can turn a promising project into a maintenance nightmare.

But there’s a hero in this story: constants. They give us a way to write code that’s logical, clean, and efficient. It’s like having a well-organized toolbox where everything has its place.

So next time you’re tempted to hard code a value, think about the future you, the one who has to maintain that code. Use constants like SAMPLE_SIZE = 120 or NR_IMPUTATIONS = 20, and let your code shine with clarity and elegance.

Remember, coding isn’t just about solving problems; it’s about creating solutions that last. Let’s make our code a masterpiece, not a puzzle.

Inefficient Use of Packages

Inefficient Use of Packages: Finding the Sweet Spot

We’ve all heard the saying, “Too much of a good thing can be bad.” When it comes to programming, this adage rings true, especially with the use of packages. It’s like being at a buffet; you want to enjoy the variety without overloading your plate.

Balancing Efficiency with Complexity: The Art of Juggling

Including packages in statistical programming can make your life easier and your code safer. It’s delegating responsibility, like handing off some heavy lifting to a friend. But like a juggler with too many balls, including too many packages can lead to complexity and inefficiency. Let’s break it down:

  • Efficiency: Using packages saves time and effort. It’s like having a toolbox filled with specialized tools that do the job for you.
  • Complexity: More packages mean more dependencies. And with more dependencies, you might find yourself tangled in a web of compatibility and maintenance issues.

Unnecessary Dependencies: The Roadblocks to Reproducibility

In the world of programming, reproducibility is key. It’s about making sure that your code works the same way every time, on every system. But too many packages can be like roadblocks on the path to reproducibility:

  • Slow Down: More packages can slow down your code, like a traffic jam slowing down your drive home.
  • Maintenance: The more packages you include, the more you have to maintain. It’s like having a garden filled with plants; they all need watering, but some might just be weeds.

Best Practices for Including Packages: The Golden Rules

So how do you strike the right balance? Here are some golden rules to live by:

  1. Keep it Minimal: Only include the packages that you really need. It’s like packing for a trip; you wouldn’t take your whole wardrobe, would you?
  2. Embrace Vectorized Operations: They’re faster than loops and can significantly speed up your code. Think of it as taking the express train instead of the local.
  3. Avoid Unnecessary Copying: Don’t duplicate data when you can reference the original. It’s like having a map instead of drawing your own every time you go somewhere.
  4. Profile Your Code: Identify bottlenecks and areas for optimization. It’s like a health check-up for your code, pinpointing where it needs a boost.
  5. Choose the Right Package: Different packages have different strengths. Pick the one that fits your task and audience like a well-tailored suit.
