Multistage Linear Genomic Selection Indices (Chapter 9)

Description

Implements multistage genomic selection index methods from Chapter 9. These methods combine genomic estimated breeding values (GEBVs) across multiple stages with covariance adjustments due to selection effects using Cochran/Cunningham's method.

Methods included: - MLGSI: Multistage Linear Genomic Selection Index (Section 9.4) - MRLGSI: Multistage Restricted Linear Genomic Selection Index (Section 9.5) - MPPG-LGSI: Multistage Predetermined Proportional Gain LGSI (Section 9.6)

All implementations use C++ primitives for mathematical operations.
