Specify a GLMM iwht a normal mixture in the random effects

lcMethodMixAK_GLMM(
  fixed,
  random,
  time = getOption("latrend.time"),
  id = getOption("latrend.id"),
  nClusters = 2,
  ...
)

Arguments

fixed

A formula specifying the fixed effects of the model, including the response. Creates the y and x arguments for the call to mixAK::GLMM_MCMC.

random

A formula specifying the random effects of the model, including the random intercept. Creates the z and random.intercept arguments for the call to mixAK::GLMM_MCMC.

time

The name of the time variable.

id

The name of the trajectory identifier variable. This is used to generate the id vector argument for the call to mixAK::GLMM_MCMC.

nClusters

The number of clusters.

...

Arguments passed to mixAK::GLMM_MCMC. The following external arguments are ignored: y, x, z, random.intercept, silent.

Note

This method currently does not appear to work under R 4.2 due to an error triggered by the mixAK package during fitting.
