In this tutorial, we will learn how to compute Pearson correlation of multiple variables. We will use two approaches to compute Pearson correlation of multiple variables in a matrix or dataframe. First we will show how to use cor() function in R to compute Pearson correlation of all variables against all variables. Then we will… Continue reading How to Compute Pearson Correlation of Multiple Variables

Computing Correlation with R
In this tutorial, we will learn how to compute correlation between two numerical variables in R using cor() function available in base R. Correlation between two numerical variables can range from -1 to +1, where -ve values suggest these two variables negatively correlated and positive value suggest that the variables are positively correlated. When there… Continue reading Computing Correlation with R
