check_inputs {mixl}

Check the inputs to the estimate function

Description

This function checks the start_vlaues, data, availabilities, draws and fixedparams for validity. If this function runs without error, then the inputs are valid for the maxLikelihood function. These checks are important, because an error in the internal C++ code will cause the Rstudio session to crash. Incidentally, if there is concern of this happening, it is recommended to run the script from the command line, using Rscript.

Usage

check_inputs(
  model_spec,
  start_values,
  data,
  availabilities,
  draws,
  fixedparam,
  weights
)
