Fixed-effects-only fitted values from an asreml model — get_fixed_fit

Returns the fitted values based on fixed effects only (\(\hat{y} = X\hat{\beta}\)), excluding all random effects.

Usage

get_fixed_fit_asreml(model, source = list())

Arguments

model: An object of class "asreml", fitted with model.frame = TRUE.
source: The known genomic relationship matrix (GRM) used in model fitted using asreml::vm(), provided as a named list. When not provided (an empty list by default), the GRM variable used for vm calling will be searched in the global environment.

Value

A numeric vector of length \(N\), giving the fixed-effects-only fitted value for each observation.

Details

This function reconstructs the fixed-effect design matrix from the stored model frame and multiplies it by the estimated fixed coefficients. Sparse fixed terms (if any) are included.

Random effects (BLUPs) are not included.
