Complete Sample Likelihood Estimation and Inference for Single and Multi-Stage Sample Surveys

In the analysis of sample surveys, accounting for informative sampling design is critical to ensure estimates of model parameters such as regression coefficients are not systematically biased. One popular solution is maximum pseudo-likelihood estimation, which incorporates weight...

Fast robust additive models using gamma-divergence

Abstract Additive models offer a flexible framework for modeling nonlinear relationships between predictors and a continuous response variable, where nonparametric terms are commonly modeled via penalized splines. However, such models can be sensitive to outliers, leading to pote...
