lcMethodLcmmGBTM: Specify GBTM method

Description

Group-based trajectory modeling through fixed-effects modeling.

Usage

lcMethodLcmmGBTM(
  fixed,
  mixture = ~1,
  classmb = ~1,
  time = getOption("latrend.time"),
  id = getOption("latrend.id"),
  nClusters = 2,
  ...
)

Arguments

fixed

The fixed effects formula.

mixture

The mixture-specific effects formula. See lcmm::hlme for details.

classmb

The cluster membership formula for the multinomial logistic model. See lcmm::hlme for details.

time

The name of the time variable.

id

The name of the trajectory identifier variable. This replaces the subject argument of lcmm::hlme.

nClusters

The number of clusters to fit. This replaces the ng argument of lcmm::hlme.

...

Arguments passed to lcmm::hlme. The following arguments are ignored: data, fixed, random, mixture, subject, classmb, returndata, ng, verbose, subset.
