Re: AR/HR Stats...
At a quick glance of the PA reports, it looks like you might be able to find some information that can be used for an analysis of some of this. I'm not sure the QDMA report will provide any usable data on PA as its pretty much a summary of 1997-1999 and the buck harvest data in the tables only has information for 2 of the years. 2 years won't show a trend.
If your interested, I have around 20 or so years of harvest data from our hunting club here in GA. Its not PA, but its an interesting data set with age, buck/doe, points, live weight, dressed weight, and a few other variables. I'm planning on trying to analyze it in the next few weeks before our Spring meeting. The club changed from a statewide regs club to QDM about 10-12 years ago so there would be some good data on both sides of this change. Let me know if you interested in using it.
What kind of analyses are you learning? ANOVA, linear regression, logistic regression? I didn't do well in my stats class at IUP when I was there, but really enjoyed the 4 classes I took in graduate school and did well too. The key was having datasets that I was interested in to learn the basics.
