get_qda_scaling {thamesmix}R Documentation

Calculates the weights of the function W described in Metodiev et al. (2025).

Description

Calculates the weights of the function W described in Metodiev et al. (2025).

Usage

get_qda_scaling(G, sims, center = NULL)

Arguments

G

number of components

sims

n_simul x G x (u+1) array of parameters sampled from the posterior, where n_simul is the number of simulations from the posterior, G is the number of components, u is the number of mixture component parameters (parameter u+1 is the mixture weight)

center

optional, means of the mixture component parameters

Value

a named list including the weights (i.e., means and covariances)
