This dissertation develops three generalized semiparametric regression models (GSPRMs)<br/>as an extension of parametric generalized linear models (GLMs) to address the dual chal-<br/>lenges of excess zeros and nonlinear covariate effects in count data and proportion data. Two<br/>estimators are developed for these models: penalized smoothing splines (Ps) and P-splines<br/>(Pb). Within the GSPRMs framework, three specific models are developed, each estimated<br/>using both developed estimators. First, the semiparametric partially Poisson (SPPO) regres-<br/>sion model captures nonparametric covariate effects in standard count data. Second, the<br/>semiparametric partially zero-inflated Poisson (SPZIP) regression model incorporates logis-<br/>tic regression components to address excess zeros in count data. Third, the semiparametric<br/>partially zero-inflated Beta (SPZIBE) regression model handles proportion data with zero-<br/>inflation.<br/><br/>To evaluate the performance and applicability of these developed models, extensive sim-<br/>ulation studies and real-world applications were conducted, demonstrating their robustness<br/>and practical utility. The Pb estimator of the extended models (SPPO-Pb, SPZIP-Pb, SPZIBE-<br/>Pb) show superior performance across evaluation metrics, including Akaike Information Cri-<br/>terion (AIC), Bayesian Information Criterion (BIC), and root mean square error (RMSE),<br/>achieving RMSE reductions of 40–58 % compared to standard Poisson, zero-inflated Poisson<br/>(ZIP) and zero-inflated Beta (ZIBE) regression models estimated via maximum likelihood<br/>(ML). Real-world applications to the Biochemists dataset (count data) and the Varieties of<br/>Democracy (V-Dem) dataset, a global socio-political dataset (proportion data), validate their<br/>utility across scientific and socio-political contexts. These models provide researchers in<br/>economics, political science, and social sciences with robust, interpretable tools for analyz-<br/>ing zero-inflated (ZI) data with enhanced predictive accuracy. |
