Given two variables, this coefficient measures the degree of linear correlation between them. A value of +1 indicates perfect positive linear correlation and that of -1 indicates negative linear correlation.

Given two variables, this coefficient measures how well the relationship between the two variables can be described using a monotonic function. A Spearman coefficient of 1 indicates that one variable is a perfectly monotone function of the other.

This is used to measure the correlation between a binary variable X and a continuous variable Y.
