r2: Reliability

In sommer: Solving Mixed Model Equations in R

Reliability

Description

Calculates the reliability of BLUPs in a sommer model.

Usage

r2(object, object2=NULL)

Arguments

object	Model fitted with the mmec function.
object2	An optional model identical to object in the first argument but fitted with the argument returnParam set to TRUE to access the relationship matrices from the fitted model.

Details

The reliability method calculated is the classical animal model: R2=(G-PEV)/G

Value

result

a list with as many elements as random effects fitted containing reliabilities for individual BLUPs.
