Hello,
I am wondering if there is a robust estimation version of polr(),
similar to the lm() -> rlm(). If not, can anyone suggest a way to do
robust estimation with polr()?
Thanks,

Hello all,
This is a general stats question--I realize it is an R help list, so
tell me to go away if it is inappropriate.
I have a 2 X 2 design, and I have specified four identical path models
(one for each level of each factor). I want to test for an interaction
at each path--essentially (
n sem() and
AMOS.
I hope this helps,
John

Hello-
If I input a variance-covariance matrix and specify NA for start values,
how does sem determine the start value? Is there a default?

Hello-
I would like to remove the columns of a matrix that contain all zeros.
For example, from
x<-matrix(c(1,5,3,2,1,4,0,0,0), ncol=3,nrow=3)
I would like to remove the third column. However, because this is in a
loop I need a way to first determine which columns are all zeros, and

Hi all-
I am stumped. The code in A. returns errors at lines 14 and 15 and fails
to load series1 and series2. However, in B., if temp1 and temp2 are
called again (which returns a "Table exists" error; see lines 14-17 in
B.) series1 and series2 load correctly. Any ideas? Also-I am open to any

Does anyone know if the sem package in R can implement a stacked model
comparison, for example as in LISREL or AMOS?
Thanks,
