Correlation with significance in r
WebJan 12, 2024 · R contains an in-built function rcorr () which generates the correlation coefficients and a table of p-values for all possible column pairs of a data frame. This function basically computes the significance levels for Pearson and spearman correlations. Syntax: rcorr (x, type = c (“pearson”, “spearman”)) WebThe correlation of a sample is represented by the letter r. The range of possible values for a correlation is between -1 to +1. A positive correlation indicates a positive linear …
