error in optimization when I include constant term in Klein and Spady (np package)
Dear all,
I am trying to use the np package for the estimation of a model with Klein
and Spady's semiparametric estimator. When though, I include a constant term
( a column with 1s in X) then the following message appear:
Multistart 1 of 3...Error in optim(c(beta, h), fn = optim.fn, gr = NULL,
method = optim.method, :
non-finite value supplied by optim
So, how can I include a constant

problem on semiparametric single index estimator
Dear R-Help,
I am Deniz.
I am currently trying to replicate a semiparametric sample selection paper
and I am working on Klein and Spady estimator. I am using the npindex() and
npindexbw() functions.
The problem is, I need results for single bandwidth and when I set bandwidth
computation to "FALSE" mode, R is not optimizing anything. Here is the code
I am using:

Update of the np package (version 0.14-1)
Dear R users,
An updated version of the np package has recently been uploaded to CRAN
(version 0.14-1).
The package is briefly described in a recent issue of Rnews (October,
2007, http://cran.r-project.org/doc/Rnews/Rnews_2007-2.pdf) for those
who might be interested.
A somewhat more detailed paper that describes the np package is

npindex: specifying manual bandwiths
Dear R-users,
I am very enthusiastic about the capacities offered by the np package and
pretty fond of it.
Nevertheless, trying to estimate Ichimura and Klein and Spady models on my
data, I would like to be able to provide the npindex function with my
guesses for the bandwidth (eventually computed by other means).
The fact that the option 'bandwidth.compute' in the function npindexbw

npindex: fitted values of the function itself?
Dear list,
I am using the np package. With the npindex function I estimate a
semiparametric single index model using the method of Klein-Spady.
P(Z=1|X) = G(X?b)
I don?t have any problems to calculated the fitted values and standard
errors X?b:
bw = npindexbw(xdat=x, ydat=y_bi, method="kleinspady", nmulti=2)

sum of functions
Dear all,
I would like to create a code for semiparametric Klein and Spady's
estimator. For that I created a function that provides the log-likelihood
function for each observation (so it is a function of betas and i, where i
denotes the observation). Now, in order to maximize the log-likelihood
function, I have to sum these log-likelihood functions for each i and so to
get another function

[asterisk-ss7]Chan_ss7 issue
Dear all,
Do you have come acrross with this issue. My ss7 link get fluctuating. It
use chan_ss7 version 1.0.95-beta.
I have 8 E1s running on a DL380 server with Digium E1 cards ( 4 port cards).
This enable to have calls from sip to ss7 and vice versa. However ss7 links
are not stable.

[gam] [mgcv] Question in integrating a eiker-white "sandwich" VCV estimator into GAM
Dear List,
I'm just teaching myself semi-parametric techniques. Apologies in
advance for the long post.
I've got observational data and a longitudinal, semi-parametric model
that I want to fit in GAM (or potentially something equivalent), and I'm
not sure how to do it. I'm posting this to ask whether it is possible
to do what I want to do using "canned" commands

Queue not dialing out to cell phone for some reason

I have queues.conf setup with a group like so:

Differences in masq from 1.4 -> 2.0?
In the panic of replacing our firewall(s) earlier in the week, we ended up
moving our original shorewall 1.4 config onto a machine with 2.0.10
already installed, overwriting all the 2.0.10 config files.
Most things seem to work fine, except for our masq entries. I''ve examined
the default 2.0.10 files compared with our 1.4 files, and can''t spot the
problem. What am I missing?

semiparametric fractional autoregressive model
folks,
does anyone know if the SEMIFAR model has been implemented in R? i see that there's a S-FinMetrics function SEMIFAR() that does the job, but I have no access to that software. essentially, this semiparametric fractional autoregressive model introduces a deterministic trend to the FARIMA(p,d,0) model (which, as i understand it, takes care of the random trend and short and long memory).
