DOI: 10.1002/sim.8844

Abstract: Dental caries (i.e., cavities) is one of the most common chronic childhood diseases and may continue to progress throughout a person's lifetime. The Iowa Fluoride Study (IFS) was designed to investigate the effects of various… read more here.

DOI: 10.1080/00949655.2019.1590580

Abstract: Abstract While excess zeros are often thought to cause data over-dispersion (i.e. when the variance exceeds the mean), this implication is not absolute. One should instead consider a flexible class of distributions that can address… read more here.

DOI: 10.1080/00949655.2024.2421317

Abstract: Recent studies focus on modelling count data, which often shows overdispersion or underdispersion. The Conway–Maxwell–Poisson (COMP) regression model effectively handles such dispersion. However, multicollinearity can negatively impact the maximum likelihood estimator (MLE) by increasing variance.… read more here.

DOI: 10.1080/03610926.2025.2484449

Abstract: Abstract In the literature of generalized linear models (GLMs), there have been many shrinkage estimation methods in the presence of multicollinearity. Applications of these estimators are often done on logistic, Poisson, gamma, and negative binomial… read more here.

DOI: 10.1162/neco_a_01593

Abstract: In many areas of the brain, neural spiking activity covaries with features of the external world, such as sensory stimuli or an animal's movement. Experimental findings suggest that the variability of neural activity changes over… read more here.

DOI: 10.3390/e25010126

Abstract: Binomial autoregressive models are frequently used for modeling bounded time series counts. However, they are not well developed for more complex bounded time series counts of the occurrence of n exchangeable and dependent units, which… read more here.
