xmu_describe_data_WLSR Documentation

Determine if a dataset will need statistics for the means if used in a WLS model.

Description

Given either a data.frame or raw mxData, this function determines whether mxFitFunctionWLS() will generate expectations for means.

Usage

xmu_describe_data_WLS(
  data,
  allContinuousMethod = c("cumulants", "marginals"),
  verbose = FALSE
)

Arguments

data

The raw data being used in a mxFitFunctionWLS() model.

allContinuousMethod

the method used to process data when all columns are continuous (default = "cumulants")

verbose

Whether or not to report diagnostics.

Details

All-continuous models processed using the "cumulants" method LACK means, while all continuous processed with allContinuousMethod = "marginals" will HAVE means.

When data are not all continuous, means are modeled and allContinuousMethod is ignored.

Value

  • list describing the data.
