Maximum Likelihood Estimation for Semiparametric Density Ratio Model

Maximum Likelihood Estimation for Semiparametric Density Ratio Model

In the statistical literature, the conditional density model specification is commonly used to study regression effects. One attractive model is the semiparametric density ratio model, under which the conditional density function is the product of an unknown baseline density function and a known parametric function containing the covariate information. This …
