LR.inter.cat: Likelihhod ratio test for an interaction term

In PIGE: Self Contained Gene Set Analysis for Gene- And Pathway-Environment Interaction Analysis

Description

The LR.inter.cat function performs a likelihood ratio test (LRT) for an interaction term between a categorical variable and a SNP (coded 0,1, 2) in a logistic model. The function returns the p-value of the likelihood ratio test.

Usage

  LR.inter.cat(x, formula, data, Z1)

Arguments

x	name or numeric vector corresponding to the SNP tested.
formula	an object of class "formula" : a symbolic description of the model to be fitted without the interaction term.
data	a data frame containing the variables in the model.
Z1	name of the variable which is tested in interaction with x (x:Z1).

Value

p-value of the likelihood ratio test for the interaction term.
