S.2019-06-282019-06-281976https://repositorio.unal.edu.co/handle/unal/42451In this note three aspects of the mixture of continuous distributions are considered. Firstly, a finite mixture of densities involving  [Formula Matemática] is considered and the distribution of the sum of independent variables, each from such a mixture, is obtained. Secondly, characterization of a mixture of k Gamma distributions is attempted. Filnally , non-central chi-square and doubly non-central F is discussed in relation to a finite mixture of normal distributions.application/pdfspaDerechos reservados - Universidad Nacional de Colombiahttp://creativecommons.org/licenses/by-nc/4.0/Artículo de revistahttp://bdigital.unal.edu.co/32548/info:eu-repo/semantics/openAccessFinite mixture densitiessum of independent variablesGama distributions
