This helper function is used in the semforest varimp and proximity aggregate functions.

evaluateDataLikelihood(model, data, data_type = "raw")

Arguments

A OpenMx model as used in semtree and semforest.

data

Data set to apply to a fitted model.

data_type

Type of data ("raw", "cov", "cor")

Value

Returns a -2LL model fit for the model
