Start Model for POLYCLASS
Dear all,
I have a question on how to set up the starting model in POLYCLASS and
make sure the terms in the starting model retained in the final
POLYCLASS model.
In the function POLYMARS, this can be done using the STARTMODEL option.
See below for example, I started with model
y= b0 + b1*X1 + b2*X2 + b3*X4 + b4*X5 + b5*X2*X5 + e
> m00 <- matrix(c(

anyone konw Polyclass package in R?
Hi everyone:
Polyclass is a polytomous logistic regression model using
linear splines and their tensor products. It provides estimates for
conditional class probabilities which can then be used to predict class
labels. I know there is Polyclass package in S-plus. So I'm wondering if
there is a corresponding package i...

Fractional brownian motion
Dear All;
I have used fbmSim to simulate a fbm sequence, however, when I tried to
estimate the Hurst effect, none of the nine procedures gave me an answer
close enough to the real value, which is 0.5 (n=1000). So, would you please
advice,
1. which is the best method to estimate the H among the 9 mehods, R/S,
higuchi or Whittle?
2. how to choose the levels (default=50), minnpts, cutoff values or

problem with indexing a zoo object
My problem is the following : I create 2 zoo objects and then I try to
subset one of them using logic. indicesthatpass is a vector of trues and
falses but when I send it into bckret, it returns an empty bckret.
Obviously it has something to do with bckret being a zoo object and if I
do the same subsctripting off of coredata(bckret), I'm confident it will
work. But, I need to keep the minute

need help on R
Hi,
I am working on a modeling project for PMI-Australia and interested in
using R, especially POLYMARS or PLYCLASS. I use SAS /PC on WINDOWS for
the statistical analyses including Modeling. I got R downloaded to the
system but can't figure out how to interface with SAS so that I could
use SAS datasets already in place.
Also I could not find POLYMARS on the library packages. I need to know
