mtdt: Transmission/disequilibrium test of a multiallelic marker

In gap: Genetic Analysis Package

Transmission/disequilibrium test of a multiallelic marker

Description

Transmission/disequilibrium test of a multiallelic marker

Usage

mtdt(x, n.sim = 0)

Arguments

x	the data table.
n.sim	the number of simulations.

Details

This function calculates transmission-disequilibrium statistics involving multiallelic marker. Inside the function are tril and triu used to obtain lower and upper triangular matrices.

Value

It returned list contains the following components:

• SE Spielman-Ewens Chi-square from the observed data.

• ST Stuart or score Statistic from the observed data.

• pSE the simulated p value.

• sSE standard error of the simulated p value.

• pST the simulated p value.

• sST standard error of the simulated p value.
