Specify a MixTVEM

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

Arguments

formula: A formula excluding the time component. Time-invariant covariates are detected automatically as these are a special case in MixTVEM.
formula.mb: A formula for cluster-membership prediction. Covariates must be time-invariant. Furthermore, the formula must contain an intercept.
time: The name of the time variable.
id: The name of the trajectory identifier variable.
nClusters: The number of clusters. This replaces the numClasses argument of the TVEMMixNormal function call.
...: Arguments passed to the TVEMMixNormal() function. The following optional arguments are ignored: doPlot, getSEs, numClasses.

Note

In order to use this method, you must download and source MixTVEM.R. See the reference below.
