st: markov transition model
There have been quite a few postings regarding
estimating a multiple state (more than 2) markov
transition model, including the two postings in the
following. I am wondering if anyone has suggestions
about this. Also, there is this paper titled "Using
Stata's -ml method d2- to estimate a multi-state
Markov transition model" by Thomas BŁttner
(firstname.lastname@example.org). I am wondering if anyone has
used this method and what is the converging speed and
results, since -ml- with -d2- is no easy job. It
seems that I cannot get hold of Mr. BŁttner via the
no-longer valid email address.
Any information in this regard will be highly
Dear David Epstein,
A couple years back you posted this (see below)
message -- I am extremely interested in the your
solution to this problem. I am estimating a dynamic
multinomial logit model and would like to create a
transition matrix of the conditional probabilities.
Thank you for the help.
just wondering whether anyone has coded transition
models, also known as
> Markov models, for 3 or more variables. That is, say
a system has 3

Pr(y_t+1=2 | y_t=1), and so
