EnglishAn important challenge in microarray data analysis is the detection of genes which are differentially expressed across different types of experimental conditions. We provide a nite mixture model aimed at clustering genes and experimental conditions, where the partition of experimental conditions may be known or unknown. In particular, the idea is to adopt a nite mixture approach with mean/covariance reparameterization, where an explicit distinction among upregulated genes, down-regulated genes, non-regulated genes (with respect to a reference probe) is made; moreover, within each of these groups genes that are differentially expressed between two or more types of experimental conditions may be identified.

We provide a finite mixture model aimed at clustering genes and experimental conditions, where the partition of experimental conditions may be known or unknown. In particular, the idea is to adopt a finite mixture approach with mean/covariance reparameterization, where an explicit distinction among up-regulated genes, down-regulated genes, non-regulated genes (with respect to a reference probe) is made
