Group-based trajectory modeling using flexmix

Description

Fits a GBTM based on the flexmix::FLXMRglm driver.

Usage

lcMethodFlexmixGBTM(
  formula,
  formula.mb = ~1,
  time = getOption("latrend.time"),
  id = getOption("latrend.id"),
  nClusters = 2,
  ...
)

Arguments

`formula`	A `formula` specifying the model.
`formula.mb`	A `formula` specifying the class membership model. By default, an intercept-only model is used.
`time`	The name of the time variable.
`id`	The name of the trajectory identifier variable.
`nClusters`	The number of clusters to estimate.
`...`	Arguments passed to flexmix::flexmix or flexmix::FLXMRglm. The following arguments are ignored: data, k, trace.
