In sommer: Solving Mixed Model Equations in R

Two-way id by features table

Description

H creates a two way id by features table that can be used as the H argument in the rrc function that extracts latent covariates.

Usage

  H(timevar=NULL, idvar=NULL, response=NULL, Gu=NULL)

Arguments

timevar	vector of the dataset containing the variable to be used to form columns in the wide table.
idvar	vector of the dataset containing the variable to be used to form rows in the wide table.
response	vector of the dataset containing the response variable to be used to fill the cells of the wide table.
Gu	an optional covariance matrix (not the inverse) between levels of the idvar in case a sparse (unbalanced) design between timevar and idvar exist.

Details

This is just an aggregate, reshape and imputation of a long format table to a wide format table.

Value

$H

two way table of id by features effects.
