| dc.description.abstract | En el presente artículo se discute un modelo de mezclas finitas para Segmentación de mercados. Cuando el modelo de mezclas finitas tiene una estructura completa el método de máxima verosimilitud de estimaciones apropiadas de los vectores de medias y matrices de covarianzas. Al imponer restricciones sobre la estructura del modelo se logra estimar los parámetros. En el artículo se muestra una aplicación de agrupamiento basado en el método de estimación de densidades para un modelo mixto Gaussiano y se discute el método de regularización de Tikhono. | spa |
| dc.description.abstractenglish | In this article, a finite mixture model for market segmentation is discussed. When the finite mixture model has a complete structure, the maximum likelihood method of appropriate estimates of the vectors of means and covariance matrices. By imposing restrictions on the structure of the model it is possible to estimate the parameters. The article shows a clustering application based on the density estimation method for a Gaussian mixed model and discusses the Tikhono regularization method. | spa |
