Beta-trees: Multivariate histograms with confidence statements
Guenther Walther, Qian Zhao
Multivariate histograms are difficult to construct due to the curse of dimensionality. Motivated by -d trees in computer science, we show how to construct an efficient data-adap…
Credibility Theory Based on Winsorizing
Qian Zhao, Chudamani Poudyal
The classical Bühlmann credibility model has been widely applied to premium estimation for group insurance contracts and other insurance types. In this paper, we develop a robust B…
An Adaptively Resized Parametric Bootstrap for Inference in High-dimensional Generalized Linear Models
Qian Zhao, Emmanuel J. Candes
Accurate statistical inference in logistic regression models remains a critical challenge when the ratio between the number of parameters and sample size is not negligible. This is…
Method of Winsorized Moments for Robust Fitting of Truncated and Censored Lognormal Distributions
Chudamani Poudyal, Qian Zhao, Vytaras Brazauskas
When constructing parametric models to predict the cost of future claims, several important details have to be taken into account: (i) models should be designed to accommodate dedu…
