Cluster-Based Bayesian SIRD Modeling of Chickenpox Epidemiology in India
Nayana Mukherjee, Chitradipa Chakraborty
This study presents a cluster-based Bayesian SIRD model to analyze the epidemiology of chickenpox (varicella) in India, utilizing data from 1990 to 2021. We employed an age-structu…
A Latent Class Bayesian Model for Multivariate Longitudinal Outcomes with Excess Zeros
Chitradipa Chakraborty, Kiranmoy Das
Latent class models have been successfully used to handle complex datasets in different disciplines. For longitudinal outcomes, we often get a trajectory of the outcome for each in…
Bayesian Modeling of Long-Term Dynamics in Indian Temperature Extremes
Chitradipa Chakraborty
Annual maximum temperature data provides crucial insights into the impacts of climate change, especially for regions like India, where temperature variations have significant impli…
Bayesian Hybrid Machine Learning of Gallstone Risk
Chitradipa Chakraborty, Nayana Mukherjee
Gallstone disease is a complex, multifactorial condition with significant global health burdens. Identifying underlying risk factors and their interactions is crucial for early dia…
Testing Multivariate Scatter Parameter in Elliptical Model based on Forward Search Method
Chitradipa Chakraborty
In this article, we establish a test for multivariate scatter parameter in elliptical model, where the location parameter is known, and the scatter parameter is estimated by the mu…
A Test for Multivariate Location Parameter in Elliptical Model based on Forward Search Method
Chitradipa Chakraborty, Subhra Sankar Dhar
In this article, we develop a test for multivariate location parameter in elliptical model based on the forward search estimator for a specified scatter matrix. Here, we study the…
