Test longitudinal measurement invariance

This function automatically runs 4 automatically generated measurement invariance models. This may not be appropriate and it might be more useful to generate lavaan syntax using long_minvariance_syntax function for each model separately and run confirmatory factor analyses using the cfa function from lavaan.

minvariance(
  data,
  var_list,
  add = NULL,
  remove = NULL,
  details = FALSE,
  return = c("fit_statistics", "model_tests", "lavaan_objects", "lavaan_syntax", "all")
)

Arguments

data	Data in wide format (one row for each participant, one column for each item at each time point)
var_list	List specifying the variable names for each time point. The number of variable names need to be identical at each time point (same measure).
add	String, lavaan syntax to be added to the model
remove	List, remove specific parts of the automatically generated model
details	Return details of selected output selected in return argument
return	What should be returned ("fit_statistics", "model_tests", "lavaan_objects", "lavaan_syntax", "all")
measure_name	String, name of the measure
time_str	String, prefix of the point specifier
item_str	String, prefix of the item specifier
