Dear Allstat users, 
I have two very general questions about Poisson Regression Analysis. 
I am relatively new to this topic but I tried to document myself as much as I could. The explanations I found in the web were too incomplete or too difficult for me. 
The two questions are: 
 
1. Given a response variable Y and n explanatory variables X1, ..., Xn, drawing a plot for each Xi against Y can I already draw some preliminary conclusions? (i.e. I can understand that I likely get rid of an explanatory variable or I likely need a polynomial regression for an explanatory variable or a transformation is needed, ...) 
2. Given a dummy variable XD, I can simply add it to the other explanatory variables or I can link it to a particular explanatory variable Xi. How can I understand the right choice? And in the second case, how can I understand to which explanatory variable Xi I should link XD? 
 
I hope that somebody can give me some useful hints. 
 
Thank you for your help 
Stefano Sofia
