Genotype-to-Phenotype map: Genotype-to-Phenotype Mapping

Description

The Genotype-to-Phenotype map is a vector providing the estimate of the genotypic value for any multi-locus genotype. The estimates may be computed from linearRegression or multilinearRegression.

Usage

GPmap(obj)

Value

Returns a matrix with two columns: the first one is the estimate of genotypic effects, the second one the standard error of this estimate.

Arguments

obj

An object of class "noia.linear" or "noia.multilinear".
