Description

This function calculates the pearson correlation of two vectors of numbers.

Usage

pearson_(x,y)

Arguments

x

Should be a vector

y

Should be a vector

Details

To calculate the pearson correlation, the user should give two vectors of numbers. The result is the covariance of the two vectors of numbers divided by the product of their standard deviations. The pearson correlation formule is the following:

Value

Numeric, the pearson correlation of two vectors of numbers.

Note

A vector is created by c(), like c(1,2,3,4,5) creates a vector with the numbers: 1,2,3,4,5
