MixStable (version 0.1.0)

em_estimate_stable_from_cdf_with_gibbs: EM algorithm for alpha-stable mixture using CDF-based ECF and Gibbs M-step

Description

Performs EM estimation of a two-component alpha-stable mixture using a simplified empirical characteristic function derived from the cumulative distribution function (CDF), with the M-step replaced by Gibbs sampling.

Usage

em_estimate_stable_from_cdf_with_gibbs(data, max_iter = 100, tol = 1e-04)

Value

A list with estimated component parameters (alpha, beta, gamma, delta) and mixture weight (w).

Arguments

data

Numeric vector of observations.

max_iter

Maximum number of EM iterations.

tol

Convergence tolerance on log-likelihood.
