Hi all,
I have a variable for which I cannot reject that the mean is zero, but
the point estimate is postive. I am interested in testing whether the
distribution of that variable is better described by a single normal
density with mean zero or by the weighted sum of two normal densities:
one with mean zero and one with positive mean. Ideally I would want
to let both the weights and the value of the positive mean be
determined by the test. Does anyone know if there's a way to do
something like this in Stata or of a reference for such a technique?
Thanks!
