Significant and Not Significant Are Not Significantly Different

One significant result and one nonsignificant result do not show that two effects differ. Test the difference itself, and here is how to do it in R.

Cluster Analysis

Explore the fascinating world of cluster analysis using R. Discover various clustering techniques, such as hierarchical clustering, k-means clustering, and more, as you delve into the process of grouping similar observations together to uncover patterns and structures in your data.

MANOVA Analysis: Unveiling Multivariate Patterns with R and Python

Learn about the fundamental concepts of MANOVA in R and Python.

Use R in Jupyter Notebook

In this post, I have showed complete procedure of enabling R kernal for Jupyter Notebook, so that you can use R in Jupyter Notebook.

The Kaplan-Meier Estimatior in R

In this post, we will see how to estimate the survival function in this method using R. Note that, the Kaplan–Meier estimator, often known as the product limit estimator, is a non-parametric statistic used to estimate the survival function using lifetime...

Shapiro Wilk Test using R

Samuel Sanford Shapiro and Martin Wilk developed a non-parametric test in 1965 to check the normality of the data, which was later named after them as Shapiro-Wilk test.

Principal Component Analysis - Theory and Application with R

PCA is a technique to transform the original set of variables into a smaller set of linear combination of variables so that most of the statistical information is preserved by those linear combinations. Before diving into the PCA, there are a few things one should be aware of...

Complete guide to bar plot using ggplot2

R is great for data visualization. One of the amazing packages in visualization in R is the ggplot2. Hadley Wickham created ggplot2 in 2005 as an implementation of Leland Wilkinson's Grammar of Graphics. It divides graphs into semantic components like scales ...
