1/ 🏗️ Mastering R's Object-Oriented Programming: S3, S4, and R6 Systems 🤖 Let's unravel the mysteries of R's object-oriented systems, and learn how to create flexible and reusable code! Join the thread for insights and examples. #rstats#OOP#datascience
2/ 🔎 S3 System: The most widely used and simplest OOP system in R. Create classes using "class()" and define generic functions with "UseMethod()". S3 is informal, making it both easy to use and prone to errors. #S3#OOP#RStats#DataScience
3/ 🛠️ Example - S3: Define a simple "Person" class and a "greet()" generic function. #S3#OOP#RStats#DataScience
4/ 🔬 S4 System: A more formal and strict OOP system, S4 introduces class definitions, validation, and multiple dispatch. Create classes using "setClass()" and methods with "setMethod()". #S4#OOP#RStats#DataScience
6/ 🚀 R6 System: A modern and powerful OOP system, R6 introduces reference classes, making it easier to work with mutable objects. Create R6 classes with the "R6::R6Class()" function. #R6#OOP#RStats#DataScience
8/ 🤔 Which system to use? S3 is suitable for small projects and quick prototypes. S4 is a better choice for larger projects and package development. R6 is recommended for complex projects requiring mutable objects and advanced OOP features. #RStats#OOP#DataScience

1/🧵✨Occam's razor is a principle that states that the simplest explanation is often the best one. But did you know that it can also be applied to statistics? Let's dive into how Occam's razor helps us make better decisions in data analysis. #OccamsRazor#Statistics#DataScience
2/ 📏 Occam's razor is based on the idea of "parsimony" - the preference for simpler solutions. In statistics, this means choosing models that are less complex but still accurate in predicting outcomes. #Simplicity#DataScience
3/ 📊 Overfitting is a common problem in statistics, where a model becomes too complex and captures noise rather than the underlying trend. Occam's razor helps us avoid overfitting by prioritizing simpler models with fewer parameters. #Overfitting#ModelSelection#DataScience
Hello #Rstats community! Today, we're going to explore the Law of Large Numbers (LLN), a fundamental concept in probability theory, and how to demonstrate it using R. Get ready for some code! 🚀
LLN states that as the number of trials (n) in a random experiment increases, the average of the outcomes converges to the expected value. In other words, the more we repeat an experiment, the closer we get to the true probability.
Imagine flipping a fair coin. The probability of getting heads (H) is 0.5. As we increase the number of flips, the proportion of H should approach 0.5. Let's see this in action with R!
1/🧵 Welcome to this thread on the Central Limit Theorem (CLT), a key concept in statistics! We'll cover what the CLT is, why it's essential, and how to demonstrate it using R. Grab a cup of coffee and let's dive in! ☕️ #statistics#datascience#rstats
2/📚 The Central Limit Theorem states that the distribution of sample means approaches a normal distribution as the sample size (n) increases, given that the population has a finite mean and variance. It's a cornerstone of inferential statistics! #CLT#DataScience#RStats
3/🔑 Why is the CLT important? It allows us to make inferences about population parameters using sample data. Since many statistical tests assume normality, CLT gives us the foundation to apply those tests even when the underlying population is not normally distributed. #RStats
