Formulation of the EM algorithm for a mixture of central and non-central [chi]2 distributions
The expectation-maximization (EM) algorithm is applied to a mixture of central and non-central [chi]2 distributions. The derivation is based on the writing of this mixture as an infinite mixture of exponential distributions for which the EM algorithm takes a simple form.
