Dear all,
I would like to fit a von mises mixture to my data using the EM
Algorithm.
Unfornately, existing packages (including circstats) doesn't provide
such method.
So, does anybody have written such code ?
Big thanks,
Christophe, (R newbie)
Why do you want to use the EM `algorithm'?
It will be easier to directly maximize the log likelihood, and that is a
5-mins job in R.
Take a look at the examples in MASS4 ch 16 (and see the books in the FAQ
or the scripts in the MASS package).

I have data of the following design:
NSubj were measured at Baseline (visit 1) and at 3

There is or is not a treatment.
Most interesting is the question if there is a

and baseline.

And then there's the classic case of higher frequency of cases with
