My understanding is that this represents bivariate normal
approximation of the data which uses the kernel density function to
test for inclusion within a level set. (please correct me)
In order to exclude the outlier to these ellipses/contours is it
advisable to do something like this:

Oh Hi Arne,
You may recall we visited with this before. I do not believe the problem is
algorithm specific. The algorithms I use the most often are BFGS and BHHH (or
maxBFGS and maxBHHH). For simple econometric models such as probit, Tobit, and
evening sample selection models, old and new versio

Hi Steven
Which optimisation algorithms in maxLik work better under R-3.0.3 than
under the current version of R?

Hmm. You raised an interesting point. Actually I am not having problems with
aod per se—-it is just a supporting package I need while using old R. The
essential package I need, maxLik, simply works better under R-3.0.3, for reason

If you like what the older version of the aod package does, but not
the current version,
then I think the solution is to propose an option to the aod
maintainer that would restore your
preferred algorithm into the current version, and

This question looks like a homework question. The posting guide syas that

Thanks for the help. I have a reason to continue with R-3.0.3. I used
maxLik to estimate econometric models and some of them are better
handled with R-3.0.3 (but not later)a sad reality I do not like.
Here is what I did. I downloaded

Don't choose a mirror. That will override the repos choice.
Do update R to a current version if you aren't able to debug this
yourself.
