em_estimate_stable_from_cdf: EM algorithm for mixture of alpha-stable distributions using CDF-based ECF

Description

Performs EM estimation of a two-component alpha-stable mixture using a simplified empirical characteristic function derived from the cumulative distribution function (CDF).

Usage

em_estimate_stable_from_cdf(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.
