pearson.pvalue {multivariance}

fast p-value approximation

Description

Computes the p-value of a sample using Pearson's approximation of Gaussian quadratic forms with the estimators developed by Berschneider and Böttcher in [4].

Usage

pearson.pvalue(x, vec = NA, type = "multi", ...)

Arguments

x

matrix, the rows should be iid samples

vec

vector, which indicates which columns of x are treated together as one sample. The default case treats each column as a separate sample.

type

one of "multi","total","m.multi.2","m.multi.3","all"

...

these are passed to cdms

Details

This is the method recommended in [4], i.e., using Pearson's quadratic form estimate with the unbiased finite sample estimators for the mean and variance of normalized multivariance together with the unbiased estimator for the limit skewness.
