In this post I will try to copy the calculations of SAS's PROC MCMC example 61.5 (Poisson Regression) into the various R solutions. In this post Jags, RStan, MCMCpack, LaplacesDemon solutions are shown. Compared to the first post in this series, rcppbugs

Poisson regression (how to reflect updated independent variables in the model) Posted 10-21-2017 10:23 PM (1758 views) Hello, I use SAS 9.4 and I am looking at how the presence or absence of disease at baseline year would affect the number of health care use in the n...
Adaptive Poisson Regression Modeling of Univariate Count Outcomes in SASThis chapter presents adaptive analyses of data on the incidence of non-melanoma skin cancer for women in St. Paul, Minnesota and Fort Worth, Texas, addressing how skin cancer rates for women of varying ages in these two ...
The statistical analyses (multilevel Poisson regression) were done using the procedure PROC GLIMMIX provided by the statistical software package SAS (SAS Institute Inc., 2011, p. 2805), which allows the estimation of multilevel multi-membership models as well. To compare the models, the Schwarz-...
Poisson regression with an offset is useful with grouped data. It can be done in Mplus by adding an offset variable with a coefficient fixed at one. An example of doing this in SAS GENMOD is shown at: http://v8doc.sas.com/sashtml/stat/chap29/sect6.htm The same results are obtain...

Count response regression models refer to regression models having a count as the response; e.g., hospital length of stay, number of bacterial pneumonia cases per zip code in Arizona from 2000 to 2005. Poisson regression is the basic model of this class. Having an assumption of the equality...
The SAS output of this model is shown in table1. Table 1 Analysis Of Maximum Likelihood Parameter Estimates Full size table Here the regression coefficient for npop represents the baseline incidence fitted by the model, that is the incidence (per 10.000 person-years) in 1993, in a non-smokin...
