expectation {gmgm}

Compute expectations of a Gaussian mixture model

Description

This function computes expectations of a Gaussian mixture model.

Usage

expectation(gmm, data_x = NULL)

Arguments

gmm

An object of class gmm.

data_x

A data frame or numeric matrix containing observations of the explanatory variables if conditional expectations are computed. Its columns must explicitly be named after the explanatory variables. If NULL (the default), the joint expectation is computed in a one-row matrix.

Value

A numeric matrix containing the expectations.
