By existing censor and skewness in survival data, some models such as weibull are used to analyzing survival data. In addition, parametric and semiparametric models can be obtained from baseline hazard function of Cox model to fit to survival data. However these models are popular because of their simple usage but do not consider unknown risk factors, that's why cannot introduce the be...
Methods for combining 2×2 contingency tables from multiple studies are reviewed and new methods are proposed. Methods for combining 2×2 contingency tables from multiple studies are presented in the context of three different statistical models: the constant coefficient model, the varying coefficient model, and the random coefficient model. The constant coefficient confidence intervals have unac...
We model unobserved preference heterogeneity in demand systems as random Barten scales in utility functions. These Barten scales appear as random coefficients multiplying prices in demand functions. Consumer demands are nonlinear in prices and may have unknown functional structure. We therefore prove identification of additive Generalized Random Coefficients models, defined as additive nonparam...
