latrend (version 1.3.0)

clusterProportions: Proportional size of each cluster

Description

Obtain the proportional size per cluster, with sizes between 0 and 1. By default, the cluster proportions are determined from the cluster-averaged posterior probabilities of the fitted data (as computed by the postprob() function).

Usage

# S4 method for lcModel
clusterProportions(object, ...)

Arguments

object

The lcModel to obtain the proportions from.

...

Arguments passed on to postprob

Value

A named numeric vector of length nClusters(object) with the proportional size of each cluster.

Implementation

Classes extending lcModel can override this method to return, for example, the exact estimated mixture proportions based on the model coefficients.

setMethod("clusterProportions", "lcModelExt", function(object, ...) {
  # return cluster proportion vector
})

Examples

# NOT RUN {
data(latrendData)
method <- lcMethodLMKM(Y ~ Time, id = "Id", time = "Time")
model <- latrend(method, latrendData, nClusters = 2)
clusterProportions(model)
# }
