Calculate a point-biserial correlation and its statistical significance — get.biserial.p.and.corr • BoutrosLab.statistics.general

Returns the point-biserial correlation and p-value for two variables (one being dichotomous) using a user-specified correlation metric. P-values are estimated analytically, not via permutation-testing.

Usage

get.biserial.p.and.corr(x, y, alternative = 'two.sided');

Arguments

x: Vector of numbers to analyze. Variable must be dichotomous
y: Vector of numbers to analyze
alternative: What is the null-hypothesis?

Value

Returns a two-element vector containing the point-biserial correlation and its p-value.
