MixStable (version 0.1.0)

em_estimate_stable_recursive_ecf: EM algorithm for mixture of alpha-stable distributions using recursive ECF

Description

Performs Expectation-Maximization (EM) to estimate parameters of a two-component alpha-stable mixture model using recursive kernel smoothing on the empirical characteristic function.

Usage

em_estimate_stable_recursive_ecf(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.
