I am unclear on how to fit a normal model with a skew component to a
histogram. I can, of course, compute the skew of the data set, 
but that does not tell me if it is a better model than one
without that factor. I would also like to use robust regression
because the data set appears to have a few outliers. References?
For those interested, the data is a histogram of the lumimosities
of low mass stars. Email or post.
