In semtree: Recursive Partitioning for Structural Equation Models

Compute the Negative Two-Loglikelihood of some data given a model (either OpenMx or lavaan)

Description

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

Usage

evaluateDataLikelihood(
  model,
  data,
  data_type = "raw",
  loglik = c("default", "model", "mvn")
)

Arguments

model	A model as used in semtree and semforest.
data	Data set to apply to a fitted model.
data_type	Type of data ("raw", "cov", "cor")
loglik	Character. Either 'model' for model-based evaluation or 'mvn' for multivariate normal density.

Value

Returns a -2LL model fit for the model
