artificialPhenotypes: Create a set of artificial phenotypes

In GROAN: Genomic Regression Workbench

Create a set of artificial phenotypes

Description

Each marker is assigned an effect based on the passed distribution. Heritability (h2) controls how much GEBV are close to phenotypes (h2=1 means no distinction, h2=0 means no correlation)

Usage

artificialPhenotypes(
  genotypes,
  mu = 0,
  h2 = 0.8,
  markersEffectDistr = "rnorm",
  ...
)

Arguments

genotypes	a samples x markers matrix of 0/1/2...ploidy
mu	intercept (added to everything)
h2	heritability (must be greater than zero, an less than or equal to one)
markersEffectDistr	name of the random generation function of the selected distribution for markers effects. It must accept n as argument indicating the number of elements to be returned.
...	further parameters are passed to markersEffectDistr

Value

a list of three elements: $GEBV is an array of genetic breeding values, $phenotypes is the array of phenotypes, and $markerEffects is an array of marker effects
