generateETA: Generate individual random effects from a multivariate normal distribution.

Description

Generate individual random effects from a multivariate normal distribution.

Usage

generateETA(n, omegaLT, omega = LTmat(omegaLT),
  eta.names = sprintf("ETA%d", 1:nrow(omega)))

Arguments

n

The number of individuals.

omegaLT

A numeric vector giving the elements of the lower triangle of the covariance matrix by row.

omega

The covariance matrix.

eta.names

A character vector of names for each random effect.

Value

An \(n \times p\) matrix, where each row contains the vector of random effects for one individual (\(p\) is the size of the covariance matrix).
