identical results with PQL and Laplace options in lmer function (package lme4)
Dear R users
I encounter a problem when i perform a generalized linear mixed model (binary data) with the lmer function (package lme4)
with R 2.1.0 on windows XP and the latest version of package "lme4" (0.96-1) and "matrix" (0.96-2)
both options "PQL" and "Laplace" for the method argument in lmer function gave me the same results (random and fixed effects

...t KalmanForecast and at the C code of KalmanFore, but it did not
help me understand what was going on.
thanks
Franck A.
btw, it has nothing to do with it, but i've done some stuff on time series
(filtering with Hodrick prescott or Baxter King, for instance) that you can

expected survival from a frailty cox model using survfit
Hello R users
Would somebody know how to estimate survival from a frailty cox model,
using the function survfit
and the argument newdata ? (or from any other way that could provide
individual expected survival
with standard error); Is the problem related to how the random term is
included in newdata ?
kfitm1 <- coxph(Surv(time,status) ~ age + sex + disease + frailty(id,

(no subject)
Hello,
I am trying to estimate a choice model with varying choice set for each
individual.
I would like to fit different kinds of model (logit ,nested logit,
probit...).
So far I have found that package *mnp* allows me to estimate a probit model
with varying choice set.
But for estimation of a logit model, I have only found function *multinom*
of package *nnet* which does not seem to allow for

Predict function npindex and npindexbw (PR#13695)
Full_Name: Maxime To
Version: 2.9
OS: WIndows
Submission from: (NULL) (81.57.236.122)
I am using the npindex and npindexbw fubctions of the NP package. I would like
to compute the predicted values of the model and tried to use the predict
function for this purpose but the function only gives me the summary of the
model but no vector of predicted values as with any other model.
Simply using the

fSeries
I'm trying to use garchFit from fSeries, with Student or Skewed Student conditionnal distribution. Let's say that eps (vector) is my series of daily log-returns:
data(EuStockMarkets)
eps = diff(log(EuStockMarkets[,"CAC"]))
library(fSeries)
g = garchFit(series = eps, formula.var = ~garch(2,2), cond.dist = "dstd")
s = g at fit$series
All the coefficients are ok
