Spearman's rho to a p-value

Description

Compute an approximate p-value against the null hypothesis that Spearman's rho is zero. This vectorizes the approximate p-value calculation in cor.test with method="spearman".

Usage

rhoToPValue(rho, n, positive = NULL)

Arguments

rho

Numeric vector of rho values.

n

Integer scalar specifying the number of observations used to compute rho.

positive

Logical scalar indicating whether to perform a one-sided test for the alternative of a positive (TRUE) or negative rho (FALSE). Default is to return statistics for both directions.

Value

If positive=NULL, a list of two numeric vectors is returned, containing p-values for the test against the alternative hypothesis in each direction.

Otherwise, a numeric vector is returned containing the p-values for the test in the specified direction.
