maxLRR Documentation

implements the maximum likelihood ratio test

Description

The maximum likelihood ratio test is a classical goodness-of-fit test for linear models. Mathematically speaking, the average residual sum of squares for an ordinary least squares (OLS) is approximated as a chi-square distribution to generate a p-value.

Usage

maxLR(X, Y)

Arguments

X

covariate matrix

Y

response vector

Details

The test is valid when the number of samples is larger than the number of covariates.

Value

p-value of the test

Examples

n <- 50
p <- 20
X <- matrix(rnorm(n*p), nrow = n, ncol = p)
Y <- rnorm(n)
stat.likelihood <- maxLR(X, Y)
