⚠️There's a newer version (2.0.710) of this package.Take me there.
selectiongain (version 1.2.1.0)
Expected gain from multistages selection
Description
This package calculate the gain from selection, which is described by Cochran (1951). For one-stage selection the gain is defined as \eqn{\Delta G (y) = i \rho_{y} \rho_{1}}, where \eqn{i} is the selection intensity, \eqn{\rho_{1}} is the correlation between the true breeding value and the selection index \eqn{y} (Utz1969). The numerical calculation is based on Tallis' algorithm (Tallis1961).
