Bayesian Modeling of Disease Case Counts: Validity of Priors and Predictors

Question: We are working on a project analyzing disease case counts across different regions in an Indian state. The administrative hierarchy follows a state → district → block structure. Our goal is to identify key predictors influencing disease case counts (target variable) for a given month and year, accounting for the temporal variation in disease spread. To model this, we assume: The intercept should never be negative since, even with zero-valued predictors, disease cases cannot be belo…

this is my previous doubt where i mentioned about my model and data
