Generalized Variable Selection Algorithms for Gaussian Process Models by LASSO-like Penalty
Zhiyong Hu, Dipak Dey
With the rapid development of modern technology, massive amounts of data with complex pattern are generated. Gaussian process models that can easily fit the non-linearity in data b…
Zero Inflated Poisson Model with Clustered Regression Coefficients: an Application to Heterogeneity Learning of Field Goal Attempts of Professional Basketball Players
Guanyu Hu, Hou-Cheng Yang, Yishu Xue +1
Although basketball is a dynamic process sport, with 5 plus 5 players competing on both offense and defense simultaneously, learning some static information is predominant for prof…
Flexible Modeling of Hurdle Conway-Maxwell-Poisson Distributions with Application to Mining Injuries
Shuang Yin, Dipak K. Dey, Emiliano A. Valdez +1
While the hurdle Poisson regression is a popular class of models for count data with excessive zeros, the link function in the binary component may be unsuitable for highly imbalan…
Skewed link regression models for imbalanced binary response with applications to life insurance
Shuang Yin, Dipak K. Dey, Emiliano A. Valdez +2
For a portfolio of life insurance policies observed for a stated period of time, e.g., one year, mortality is typically a rare event. When we examine the outcome of dying or not fr…
Spatial risk estimation in Tweedie compound Poisson double generalized linear models
Aritra Halder, Shariq Mohammed, Kun Chen +1
Tweedie exponential dispersion family constitutes a fairly rich sub-class of the celebrated exponential family. In particular, a member, compound Poisson gamma (CP-g) model has see…
An Extended Poisson Family of Life Distribution: A Unified Approach in Competitive and Complementary Risks
Pedro L. Ramos, Dipak K. Dey, Francisco Louzada +1
In this paper, we introduce a new approach to generate flexible parametric families of distributions. These models arise on competitive and complementary risks scenario, in which t…
