check_inputs: Check the inputs to the estimate function

In mixl: Simulated Maximum Likelihood Estimation of Mixed Logit Models for Large Datasets

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
)

Arguments

model_spec	The specified Model
start_values	Named vector of proposed start values for the model
data	the dataset on which to estimate
availabilities	The availabilities for the alternatives in the model specification
draws	The matrix of random draws
fixedparam	Named vector of parameters to be fixed
weights	The weights vector

Value

Nothing
