residualize {PCFAM}

Residualization and scale of the original genotype data

Description

Thus function performs a simple residualization of a row-scaled genotype dataset, removing large-scale population stratification. Output is a residualized dataset appropriate for computing correlations such that family members can be easily identified. The function assumes X is row-scaled

Usage

residualize(X)

Arguments

X

The original input genotype dataset

Details

This function pre-treatment the data before applying the findfamily function.

Value

Outputs the new row-scaled genotype matrix after residualization
