expand_subjects: Longitudinally expand a cluster

In SimTimeVar: Simulate Longitudinal Dataset with Time-Varying Correlated Covariates

Description

An internal function not intended for the user. Given a matrix of cluster means for each variable to be simulated, "expands" them into time-varying observations.

Usage

expand_subjects(mus3, n.OtherNorms, n.OtherBins, n.TBins, wcor, obs, parameters,
  zero = 1e-04)

Arguments

mus3	A matrix of cluster means for each variable.
n.OtherNorms	The number normal variables (not counting those used for generating a time-varying binary variable).
n.OtherBins	The number of static binary variables.
n.TBins	The number of time-varying binary variables.
wcor	The within-cluster correlation matrix.
obs	The number of observations to generate per cluster.
parameters	The parameters dataframe.
zero	A small number just larger than 0.

Examples

# subject means matrix (normally would be created internally within make_one_dataset)
