Re: On inappropriate hypothesis testing. Was: MIT Sexism & statistical bunk

Thanks again for the clarification, Jim. I think we are in essential agreement. To reply succinctly to your message: 1. Certainly, as a general rule one should *always* look at distributional shape as well as summary statistics. Feminists seldom do, by the way, in advancing arguments about discr

Actually, I wasn't even referring to Mr. Ulrich! I was referring to the state of the art in feminist analysis of "gender discrimination" in university faculties. I can, indeed, understand why the Landgrebian Mr. Ulrich would be sensitive. He hasn't driven me anywhere. I'm still calmly waiting fo

Re: One tailed vs. Two tailed test

Apart from making the observation that there are many applications of tests that do not involve ethical considerations, I am not at all clear how this example relates to one or two tailed testing. There is certainly an argument that when trialling a new treatment (I initially used the word 'testi

Computing the variance of cumulative survival-rate (kaplan-meier)

Hi, I found two different formula for calculating the varicance of the cumulative survival-rate (km-estimator). #1: var(S)=S^2 * \sum[d/r(r-d)] ist called Greenwood's formula #2: var(S)=S^2*(1-S)/r where S: cum. survuval-rate d: number of events r: number of individuals at risk I prefer for
