Using the covariate density defined mixtures of general linear models method of analyzing birth weight and infant mortality addresses two problems standard analysis of birth weight and infant mortality cannot:

    1. Some covariates of infant mortality may be mediated by other covariates

    2. Birth cohorts are heterogeneous
