Total (un)standardized effects in SEM?
Hi there,
as a student sociology, I'm starting to learn about SEM. The course I
follow is based on LISREL, but I want to use the SEM-package on R
parallel to it.
Using LISREL, I found it to be very usable to be able to see the
total direct and total indirect effects (standardized and
unstandardized) in the output. Can I create these effects using R? I
know how to calculate them

Bootstrap BCa confidence limits with your own resamples
I like to bootstrap regression models, saving the entire set of bootstrapped
regression coefficients for later use so that I can get confidence limits
for a whole set of contrasts derived from the coefficients. I'm finding
that ordinary bootstrap percentile confidence limits can provide poor
coverage for odds ratios for binary logistic models with small N. So I'm
exploring BCa confidence

another optimization question
Dear R list members,
Since today seems to be the day for optimization questions, I have one that
has been puzzling me:
I've been doing some work on sem, my structural-equation modelling package.
The models that the sem function in this package fits are essentially
parametrizations of the multinormal distribution. The function uses optim
and nlm sequentially to maximize a multinormal
