Statistics of mixtures with varying concentrations with application to DNA microarray data analysis
Rostyslav Maiboroda, Olena Sugakova · Journal of nonparametric statistics · 2011
A finite mixture model is considered in which the mixing probabilities vary from observation to observation. Estimation of mixture components distributions, functional moments and densities is discussed. Tests are proposed for testing hypotheses on the moments. An application to the analysis of DNA microarray data is considered.
