examples of excel

I seem to recall that while back someone posted a listing of URLS for examples of lessons in statistics using MS Excel. I wonder if anyone has that list or can recommend another source. Thanks Bill === This list is open

Looking for a statistics software catalog that I used to get (Scientific Software?)

I used to receive a catalog (I believe it was called "Scientific Software" or "Scientific and Engineering Solutions" or something like that) that sold products such as Gauss, SAS, and MathCad. Is this catalog still available? Does anyone have their phone number? Do they have a web site? Thanks

Re: hyp testing and rho

If the null hypothesis is H0: mu1-mu2=0 and the alternative is H1: mu1-mu20 What does the test say about mu1-mu2 if we reject H0 at level alpha(say at the magical 0.05)? Not much on its own. However, what if we plan a statistical experiment as follows: Given a desired power of

I agree that rho=0 as typically used is silly. Well are you are arguing then for the Bayesian framework of getting a probability distribution on rho.?? dennis roberts wrote: At 11:58 AM 4/11/00 -0400, you wrote: at the bottom it would be easy to show whether rho is more likely closer
