Summary: we propose a beta-mixture model approach to solve a variety of problems related to correlations of gene-expression levels. For example, in meta-analyses of microarray gene-expression datasets, a threshold value of correlation coefficients for gene-expression levels is used to decide whether gene-expression levels are strongly correlated across studies.

Now we’ll solve some more general applications of the mixture model. Grocers and bartenders use the mixture model to set a fair price for a product made from mixing two or more ingredients. Financial planners use the mixture model when they invest money in a variety of accounts and want to find the overall.
Because of their flexibility, mixture models are being increasingly exploited as a convenient, semiparametric way in which to model unknown distributional shapes. This is in addition to their obvious applications where there is group-structure in the data or where the aim is to explore the data for such structure, as in a cluster analysis.

This is when gmm (gaussian mixture model) comes to the picture. Basically, the core idea of this model is that it tries to model the dataset in the mixture of multiple gaussian mixtures. Gaussian mixture is a function that includes multiple gaussians equal to the total number of clusters formed.
However, semiparametric models, are often of greater interest than parametric models since the parametric assumption can be hard to meet.
