Asymptotic Theory for Multiple-Sample Semiparametric Density Ratio Models and Its Application to Mortality Forecasting

Lu, Guanhua - 2007

A multiple-sample semiparametric density ratio model, which is equivalent to a generalized logistic regression model, can be constructedby multiplicative exponential distortions of a reference distribution. Distortion functions are assumed to be nonnegative and of a known finite-dimensional...

Testing the fit of the logistic model for matched case-control studies

Chen, Li-Ching; Wang, Jiun-Yi - In: Computational Statistics & Data Analysis 57 (2013) 1, pp. 309-319

adequacy with matched case-control data get relatively less attention. In this study, we propose an omnibus goodness …-of-fit test to assess adequacy of the conditional logistic model for matched case-control data. The proposed test can be either …

Semiparametric analysis for case-control studies: a partial smoothing spline approach

Kim, Young-Ju - In: Journal of Applied Statistics 37 (2010) 6, pp. 1015-1025

Case-control data are often used in medical-related applications, and most studies have applied parametric logistic … regression to analyze such data. In this study, we investigated a semiparametric model for the analysis of case-control data by … gastric cancer case-control data to estimate the nonparametric probability function of age and regression parameters for other …

Accurate Ranking of Differentially Expressed Genes by a Distribution-Free Shrinkage Approach

Opgen-Rhein, Rainer; Strimmer, Korbinian - In: Statistical Applications in Genetics and Molecular Biology 6 (2007) 1, pp. 9-9

High-dimensional case-control analysis is encountered in many different settings in genomics. In order to rank genes accordingly, many different scores have been proposed, ranging from ad hoc modifications of the ordinary t statistic to complicated hierarchical Bayesian models. Here, we...
