guns and doctors *urgent*
Being a statistician I love these snippets. Of course the reason for providing the data in the manner given was to make a point. NOTE: I am not saying anything here re gun control, that is not the point of my reply, all I want to illustrate is a few points on interpreting statistical data.
Assuming the data is correct, consider the following:
The data essentially point out that the probability of accidential death occuring due to physician is greater than accidential death by gunshot (gun owner), well imagine a society where you were more likely to die from accidential gunshot - hummm pretty violent/grim society. On the face of it the data seem to be outrageous but think about how likely YOU are to die (at any age) from physician error vs gunshot, my money is on the physician death counter.
How many accidential deaths attributed to physicians were actually caused by the physician personally and not just logged as such because the particular physician was the attending physician and therefore on record as having oversight (may not have been directly involved).
In a study comparing one statistic to another the method of data collection has to be similar I suspect the manner of data collection on physician accidential deaths vs gunshot accidential deaths is totally different (therefore not valid to compare).
Physicians are in a life and death business one would expect mistakes to cause death, also medical science is still a hit and miss (er pun not intended) profession. Of more interest would be how many of those deaths were preventable given what we know about a patients condition etc. On the other hand ALL accidential gunshot deaths should be preventable.
What is the age demographic of the accidential deaths, here I suspect physician accidential deaths would be much older, indicating age as an accidential death covariate.
My point is think about data when they are presented, try to consider how the presenter arrived at the conclusions they did. I can tell you statistics can be made to say anything.
Right, I am off to the doctor, wish me luck

Billy thanks for your interest. I removed one of the cross bolts attaching the auger to the PHD gear bow and dug four more holes in similar soil and did not see any more "slippage" not to say there was none but didn't notice anything, I am done with that job now so have returned the PHD. I then mowed some pretty heavy grass and when the going got tough the engine labored. It struck me that if the engine was laboring then the clutch would not be slipping, right, anyway that makes me feel better about it, I guess we will see.
BTW hope you die with your guns and not by ,em. I have a few myself, I always make sure anyone who uses guns around me physically demonstrate to me that they know guns. It might be a bit anal but I feel like its my gun saftey bit. Most folk are only too happy to oblige (where is the saftey and is the breech clear etc) as responsible gun ownwers know gun saftey when they see it and you cant be too safe around guns.

Ncrunch. I have a Ph.D. (Kentucky) in monogastric nutrition with minors in statistics for both Ph.D. and MS. I am familiar with Bill Roush's work on the stocastic formulation programs he developed while still at PSU (WinFeed program), he is now with USDA. In my current job I oversee all data analysis for our research program. Most of it is linear and nonlinear mixed models (genotype amino acid evaluations etc), mulivariate regression and some principal component analysis, and the bain of my life - field trials. The rest of it is applying controlled research study data to our feed perfomance in the field. Generally the results are there but customers cant see them without a bit of help. I do a bit of work in real-time data summarization of research trials using simple interfaces like Excel, occasionally get SAS to draw a few pretty 3D graphs when the big wigs want something with the wow factor but usually they seem to get by without them. Thats about it. Do you attend any of the SAS SUGI meetings?

NCrunch, I had meant to reply but had to go on vacation (too many data). Have always enjoyed the SUGI meetings, always learn something worthwile, last year a bit of SAS code I picked up saved me DAYS of work time, so the meeting more than paid for itself. I too am glad there are other statisticians who love tractors, although if you consider the total population of statisticians its possible that some of them own tractors and then etc etc.
