Fwd: mgcv 1.4 on CRAN
mgcv 1.4 is now on CRAN. It includes new features to allow mgcv::gam to fit
almost any (quadratically) penalized GLM, plus some extra smoother classes.
New gam features
-------------------------
* Linear functionals of smooths can be included in the gam linear predictor,
allowing, e.g., functional generalized linear models/signal regression,
smooths of interval data, etc.

which coefficients for a gam(mgcv) model equation?
Dear users,
I am trying to show the equation (including coefficients from the model
estimates) for a gam model but do not understand how to.
Slide 7 from one of the authors presentations (gam-theory.pdf URL:
http://people.bath.ac.uk/sw283/mgcv/) shows a general equation
log{E(yi )} = ?+ ?xi + f (zi ) .
What I would like to do is put my model coefficients and present the
equation used. I am an

gaussian family change suggestion
Hi,
Currently the `gaussian' family's initialization code signals an error if
any response data are zero or negative and a log link is used. Given that
zero or negative response data are perfectly legitimate under the GLM
fitted using `gaussian("log")', this seems a bit unsatisfactory. Might
it be worth changing it?
The current offending code from `gaussian' is:

naresid.exclude query
x <- NA
na.act <- na.action(na.exclude(x))
y <- rep(0,0)
naresid(na.act,y)
... currently produces the result...
numeric(0)
... whereas the documentation might lead you to expect
NA
The behaviour is caused by the line
if (length(x) == 0L) return(x)
in `stats:::naresid.exclude'. Removing this line results in the behaviour I'd

According to the help file for model.frame/get_all_vars, the following should

mgcv 1.5-0
mgcv 1.5-0 is now on CRAN. Main changes are:
* REML and ML smoothness selection are now available.
* A Tweedie family has been added.
* `gam.method' has been replaced (see arguments `method' and `optimizer'
for `gam')
For other changes see the changeLog.

Cubic splines in package "mgcv"
re: Cubic splines in package "mgcv"
I don't have access to Gu (2002) but clearly the function R(x,z) defined
on p126 of Simon Wood's book is piecewise quartic, not piecewise cubic.
Like Kunio Takezawa (below) I was puzzled by the word "cubic" on p126.
As Simon Wood writes, this basis is not actually used by mgcv when
specifying bs="cr".
Maybe the point is

Fwd: Re: residual checking for GAM (mgcv)
The plots look reasonable to me. The plot of residuals against linear
predictor always looks scary when many of the fitted values are very
close to zero, so I tend to look at residuals against sqrt(fitted) in
such cases. I don't think that the presence of the zero curve is a
reason to reject the model --- it's easy to produce such plots by
fitting a completely correct model to simulated

[Fwd: REML - quasipoisson]
Hi Greg,
For quasi families I've used extended quasi-likelihood (see Mccullagh
and Nelder, Generalized Linear Models 2nd ed, section 9.6) in place of
the likelihood/quasi-likelihood in the expression for the (RE)ML score.
I hadn't realised that this was possible before the paper was published.
best,
Simon

Binning of integers with hist() function odd results (P (PR#14048)
Hi,
Thank you for responding quickly and explaining the behavior. By
adding "include.lowest=TRUE,right=FALSE" and manually including breaks
that resolved the simple test case. Next I updated my more complex
data set, which already had manually defined breaks, and that resolved
my issues there too. I have now gone in and updated all my functions
which use hist() so I

error message: .Random.seed is not an integer vector but
Thanks much Ted. I actually had just tried what you suggest here before
you posted, and resolved the problem. Thanks also for the other tips. I
wrote x = as.vector(c(1:12)) because I thought that the mode of x might be
the problem, the error message pointing to .Random.seed notwithstanding.
On a related note, I did a brief test a couple weeks back where I ran a
million random samples of 3 from

'plm'/'kinship' package on Debian Etch?
Hi Folks,
Has anyone got a compiled binary of the package 'plm'
and/or of the package 'kinship' for Debian Etch?
I'm asking because I'd like to install 'plm', but have
failed because it depends on 'kinship', and 'kinship'
refuses to compile on my Debian Etch.
The underlying reason is the Debian refuses to allow me

the classic critcisms of using Excel for statistics.

Or would the Executive Summary be: "Calc is just like Excel"?
