Add a finite-mixture wrapper to an existing UMG

Source: R/motifs.R
umg_mixture.Rd

Promotes a set of parameter or latent vertices to class-varying quantities by adding a latent class vertex with mixing edges into them, implementing the mixture move described in the accompanying article. The latent growth model of umg_growth() wrapped this way becomes a growth mixture model.

Usage

umg_mixture(model, targets, class = "c", plate = NULL)

Arguments

model

An object of class umg.

targets

Character vector of vertex names the class selects.

class

Name of the latent class vertex to add.

plate

Optional name of an existing plate to add the class vertex to (defaults to the first plate, typically the person plate).

Value

An object of class umg.

Examples

g <- umg_growth(4)
umg_mixture(g, targets = c("I", "S"))
