Negative binomial regression for count data

Dear list,
I would like to fit a negative binomial regression model as described in "Byers AL, Allore H, Gill TM, Peduzzi PN., Application of negative binomial modeling for discrete outcomes: a case study in aging research. J Clin Epidemiol. 2003 Jun;56(6):559-64" to my data in which the response is count data. There are also 10 predictors that are count data, and I have also 3

negative binomial lmer

Hi
I am running an lmer which works fine with family=poisson
mixed.model<-lmer(nobees~spray+dist+flwabund+flwdiv+round+(1|field),family="poisson",method="ML",na.action=na.omit)
But it is overdispersed. I tried using family=quasipoisson but get no P
values. This didnt worry me too much as i think my data is closer to
negative binomial but i cant find any examples of

[Patch] Fix the slow wall clock time issue in x64 SMP Vista

In x64 SMP Vista HVM guest (vcpus=2 in the configuration file), the wall
clock time is 50% slower than that in the real world. The attached patch
fixes the issue.

Trap an error from a function

Window 7
R 2.15
I am writing a simulation which generates sample sized estimates from simulated data. When I run the function shown below,
power.t.test(delta=14.02528,sd=1.945226,power=0.8,sig.level=0.05)
I get an error message:
> power.t.test(delta=14.02528,sd=1.945226,power=0.8,sig.level=0.05)
Error in uniroot(function(n) eval(p.body) - power, c(2, 1e+07)) :

Negative intercept in glm poisson model

Dear list,
I'm trying to fit a glm model using family=poisson(link = "identity"). The
problem is that the glm function fits a model with a negative intercept,
which sounds like a nonsense to me, being the response a Poisson variable.
>From a previous discussion on this list I've understood that the glm function
uses IRLS for the fitting without any constraint so it is

Implementing a ISDN home PBX

Hi,
I would like to implement a inexpensive home PBX with Asterisk. I have
an internal ISDN bus with 6 ISDN phones. I now thought, I connect a
Fritz card to my Mehrgerateanschluss (Point-to-Multipoint) supplied by
my provider and a second Fritz card to the internal bus. Will this work?
Thanks for the help,

extract all numbers from a string

Hi all,
I have been beating my head against this problem for a bit,
but I can't figure it out.
I have a series of strings of variable length, and each will
have one or more numbers, of varying format. E.g., I might
have:
tmpstr = "The first number is: 32. Another one is: 32.1.
Here's a number in scientific format, 0.3523e10, and
another, 0.3523e-10, and a negative,

Why are lagged correlations typically negative?

Recently, I was working with some lagged designs where a vector of
observations at one time was used to predict a vector of observations at
another time using a lag 1 design. In the work, I noticed a lot of
negative correlations, so I ran a simple simulation with 2 matched
points. The crude simulation example below shows that the correlation
can be -1 or +1, but interestingly if you do this

Implementing Silverman's Negative Reflection

Hi!
I'm trying to implement in R in an easy way the negative reflection method
described in Silverman (1986) on p.31, ie I have a non-negative dataset and
would like to estimate the density by applying a reflection method where the
reflected points have weight -1.
I thought there should be a way to evaluate the wanted kernel at the
required points, in other words to calculate formula (2.16):

Handling Negative value due to logarithm of probabilities.

Hi,
In continuation of the discussion of melange comments,about negative value
returned in matcher due to logarithm of probabilities.
*I**f we make K suitably large, we could clamp each log(K.Pi) to be >= 0,
and this change will only affect really low probability terms (those with
Pi < 1/K, so you can adjust K to suit):*
*W' = sum(i=1,...,n, max(log(K.Pi), 0))*

[PATCH nbdkit v2] server: utils: Make nbdkit_parse_size to reject negative values

From: Nikolay Ivanets <stenavin@gmail.com>
nbdkit_parse_size() uses strtoumax() function to parse input strings
which states:
"if there was a leading minus sign, the negation of the result of the
conversion represented as an unsigned value, unless the original
(nonnegated) value would overflow."
Later validation doesn't catch the situation when parsed value appeared
within the valid range (due to negation) but original string passed to a
function literally represented negative number.
Thus nbdkit_parse_size() treats negative values in a range [-UINT64_MAX...

[LLVMdev] Signed NaNs in APFloat arithmetic

Ok, I had forgotten about sNaNs. Doesn't the same caveat apply to
0-sNaN then though or does that not signal? Does that mean we need a
separate way to handle negate in the IR? Funnily enough, historically
I believe we were using the multiplication by -1.0 because it was a
more reliable negation that 0-x (from 3.0 until 3.3 at least). Is
there a good reason why multiplication by NaN should kill

in R when I get negative adjusted R^2 using "lm", what might be the problem?

This is a linear regression of Y onto factors...
If I take log of Y, and regress onto the factors, I got:
Multiple R-squared: 0.4023, Adjusted R-squared: 0.2731
If I don't take log of Y, and directly regress Y onto the factors, I got:
Multiple R-squared: 0.1807, Adjusted R-squared: -0.001112
Is this negative adjusted R^2 a problem?
What observation can I make here and what might

doveadm acl set negative rights not supported?

I'm trying to set an ACL with negative rights. I have no problems setting it with standard IMAP commands, but I'm unable to do it with the doveadm acl command.
I tried:

Unfortunately, this adds a (positive) ACL for the user

[PATCH] build: build mlaugeas with -Wno-shift-negative-value

The embedded copy of ocaml-augeas does Val_int(-1), which in turns
triggers warnings in newer GCC versions about "left shift of negative
value". The issue actually lies in the OCaml headers (mlvalues.h in
particular), and it was fixed in newer OCaml versions.
Since the code is actually correct, disable -Wshift-negative-value with
-Wno-shift-negative-value (checking whether the compiler
