Hi,
If you need C-program or C-functions for LMS or LTS regression you can
find one from my web-site http://www.cc.jyu.fi/~esaolli/ . The code
should be very easily integrated to your own projects.

I am a MINITAB user and don't claim to have used it with the sample sizes
your talking about. BUT, I would venture to say that it has the best
reliability analysis tools of any general statistics package out there. Only
Weibull ++ and (maybe) WeibullSmith are better. By "reliability analysis"
I'm
Hi everybody!
I am doing Tobit analysis for my research and want to test regression
hypotheses (Normality, Constant variance, Independence) using plots of
residuals. I also want to check outliers and leverage. but I am not sure
whether I could use these tests for the Tobit model (non-linear) or

Thanks in advance.

Why not introduce hypothesis testing in a binomial setting where there are
no nuisance parameters and p-values, power, alpha, beta,... may be obtained
easily and exactly from the Binomial distribution?

All of your observations about the deficiencies of data are perfectly
valid. But what do you do? Just give up because your data are messy, and
your assumptions are doubtful and all that? Go and dig ditches instead?
You can only analyse data by making assumptions - by working with models
