Logistic and Linear Regression Libraries
Hi all,
I'm trying to discover the options available to me for logistic and linear
regression. I'm doing some tests on a dataset and want to see how different
flavours of the algorithms cope.
So far for logistic regression I've tried glm(MASS) and lrm (Design) and
found there is a big difference. Is there a list anywhere detailing the
options available which details the specific

polr probit versus stata oprobit
Dear All,
I have been struggling to understand why for the housing data in MASS
library R and stata give coef. estimates that are really different. I also
tried to come up with many many examples myself (see below, of course I
did not have the set.seed command included) and all of my
`random' examples seem to give verry similar output. For the housing data,
I have changed the data into numeric
