1. ### Comparison of regression coefficients between (nested) geographic regions

Hi All, I would like to compare the effect of an explanatory variable (say X1) on a response variable (Say Y) between two geographic regions in which one is a sub-region of the other. For example, I am fitting two regression models(Y on X1), one for the city data and the other for country...
2. ### Is it possible to Reduce/Correct Bias through EM algorithm?

I am dealing with few overdispersed count models and using mixed Poisson distributions to deal with overdispsered data. I've used MLE technique to estimate the paramters, however ML estimates are lower biased. I am trying to correct the bias using advanced technquies. I have started to read...

Hi, I am looking for the theoretical method/algorithms to generate beta-binomial random variables. I would like to kindly request you to suggest me any journal paper or document to study the methods of generating beta-binomial random variables. [ I use rbetabinom function available in...
6. ### Solving Estimating Equations using R packages

Hello, I am trying to estimate e intraclass correlation parameter of of binary data using extended quasi-likelihood estimation methods. The below are the estimating equations for the mean and dispersion parameters based on beta-binomial distribution. Which, I captured from An empirical...
