dot-getGradients: .getGradients

In lessSEM: Non-Smooth Regularization for Structural Equation Models

.getGradients

Description

returns the gradients of a model of class Rcpp_SEMCpp. This is the internal model representation. Models of this class can be generated with the lessSEM:::.SEMFromLavaan-function.

Usage

.getGradients(SEM, raw)

Arguments

SEM	model of class Rcpp_SEMCpp
raw	controls if the internal transformations of lessSEM should be used. lessSEM will use an exponential function for all variances to avoid negative variances. When set to TRUE, the gradients will be given for the internal parameter representation. Set to FALSE to get the usual gradients

Value

vector with derivatives of the -2log-Likelihood with respect to each parameter
