The new semester has started and one of my first assignments has been to
find some datasets that I'd be interested in evaluating during some of my
classes.
I spent some time searching the Internet for some interesting data. The
data available on StatLib is not exactly what I'd prefer to study

All three of your models: Exponential, Gamma and Weibull are of
the form a*X^s where X is Gamma with n degrees of freedom and s
and a are additional unknown parameters.
For n=s=1 we have exponential.
For s=1 we have gamma.
For n=1 we have Weibull.
Thus fit a*X^s and use the likelihood ratio

Happy new year to all.
I frequently use Excel2000 for graphic presentation, spreadsheet maths,
simple nonlinear model fitting (using the Excel solver) with one or two
parameters, and simulations. I thought Excel2000 corrected those errors
found in the analysis tool pack and other in-built comput

Hi!
I have a series of observations of 2 random variables (say X and Y) from my
measurement data. These 2 RVs are not independent and hence f(X,Y) ~=
f(X)f(Y). Hence, I can't investigate f(X) and f(Y) separately. I tried to
plot the 2-D kernel density estimates of these 2 RVs and from the it look
