Abstract: The model of mixtures with varying concentrations is discussed. The parameterization of the first $ K$ of $ M$ components is considered. The semiparametric estimation technique based on the method of generalized estimating equations is considered. The consistency and asymptotic normality of estimators are proved. A lower bound for the dispersion matrix is found.

Keywords: Lower bound, mixture model, generalized estimating equations
