tail estimates using Generalized Pareto Distribution

Hi I would like to know if anyone knows how to estimate the tail of a distribution using either Generalised Pareto Distribution (GPD) or Generalised Gamma Distribution (GGD). I have read a paper by R.L Smith "ESTIMATING TAILS OF PROBABILITY DISTRIBUTIONS" and that paper is way too complex for

trash talk

here are some figures on how much "trash" accumulates at a number of big 10 football stadiums for home football games ... penn state generates about 40 tons ... and at ohio state, which has a stadium and fan turnout about the same as penn state, the figure is about 16/17 tons ... i have NO

Re: .05 level of significance

Pardon my interference, but I think there's some confusion regarding the events here. When I toss the first round of coins, I get about 1/2 of them heads. No problema. Then, when I toss the second time, 1/2 of *those ones that fell heads* (1/4 of the total, .5*.5) have a chance to be heads

proportional odds assumption in SUDAAN

I'm running proportional odds models for ordinal outcomes using proc multilog in SUDAAN. SUDAAN doesn't seem to provide the test for the proportional odds assumption. Can anyone tell me if that test is in fact available (as it is in SAS)?

Statistical Inference

I have noted Steve Simon's advice regarding limits on sample populations and his reference to Hahn and Meeker' book "Statistical Intervals". This is one of the most satisfying texts I have read in several years. The material is well and succinctly presented and the examples are illuminating. It
