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

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)) : f() values at end points

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, Arik

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))* Did you mean for

What happen for Negative binomial link in Lmer
Seems the message below and the thread have reveived no attention/answer. The output presented is quite tricky. Looks like if lmer (lme4 0.9975-10) has accepted a negative binomial link with reasonable estimates, although it was not designed for... What can one think about result validity ?

[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

[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?
Hi all, 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: sudo -u vmail doveadm acl set -u "user at domain" Spam user="-user at domain" lookup (notice the "-" before the username) 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
