Extract Empirical Estimating Functions

Description

A function for extracting the empirical estimating functions of a fitted lavaan model. This is the derivative of the objective function with respect to the parameter vector, evaluated at the observed (case-wise) data. In other words, this function returns the case-wise scores, evaluated at the fitted model parameters.

Usage

estfun.lavaan(object, scaling = FALSE)

Arguments

object

An object of class lavaan.

scaling

If TRUE, the scores are scaled to reflect the specific objective function used by lavaan. If FALSE (the default), the objective function is the loglikelihood function assuming multivariate normality.

Value

A n x k matrix corresponding to n observations and k parameters.
