lambda.pert {mixtools}R Documentation

Perturbation of Mixing Proportions

Description

Perturbs a set of mixing proportions by first scaling the mixing proporitons, then taking the logit of the scaled values, perturbing them, and inverting back to produce a set of new mixing proportions.

Usage

lambda.pert(lambda, pert)

Arguments

lambda A vector of length k giving the mixing proportions which are to be perturbed.
pert A vector (likely of length k-1) for which to perturb lambda. If the length is less than k-1, then values of the vector are recycled. If length is greater than k-1, then only the first k-1 values are used.

Details

This function is called by regmixMH.

Value

lambda.pert returns new lambda values perturbed by pert.
