Negative Binomial Predictions
Good Day All,
I have a negative binomial model which I have developed using the MASS
library. I now would like to develop some predictions from it.
Running the predict.glm (stats library) using type="response" gives me a
non-integer value which was rather puzzling. I would like to confirm
that this is actually the mean predicted value of the probability mass
function as opposed

Import ASCII data using a .sas program
Good Day,
I have several ASCII data files that I would like to import into R.
They all have a SAS import file which is used to bring the data into SAS
and I am hoping to use this to bring the data into R. There are lots of
variables involved and the ASCII data file is 2308 columns long so I
would certainly prefer to figure out a smart way of converting the data
to R.
The ASCII data is a

Plotting series with no data in xyplot
Good Day All,
I am working on some xyplots using the Lattice Library. My X-axis is
the date and I am reproducing charts similar to those found in the R
Gallery (see here:
http://www.sr.bham.ac.uk/~ajrs/R/gallery/plot_midday_weather_profiles.txt)
However, the key difference is that some of my data is missing (not
collected at that time). For instance, I might have a whole month that

Error message when calculating BIC
Hi All,
Could someone help me decode what this error means ?
> BIC(nb.80)
Error in log(attr(object, "nobs")) :
Non-numeric argument to mathematical function

BTW, nb.80 is a negative binomial glm model created using the MASS
library with the call at the bottom of the message
In the hopes of trying to figure this out I tried the following
workaround but it did not work

Proper / Improper scoring Rules
Hi All,
I am working on some ordinal logistic regresssions using LRM in the
Design package. My response variable has three categories (1,2,3) and

probabilities into the categories.
I had two questions:

Dear Helpers,
I just started working with R and I'm a bit overloaded with information.
My data is from marsupials reindroduced in a area. I have weight(wt),
hind foot
lenghts(pes) as continues variables and origin and gender as categorial.
condition is just the residuals i took from the model.

I can't remove wine applications!
Hi there! I have a serious issue! I tried installing a game (PES 2010) and then, because it was not running, I decided to remove the application and upgrading to wine 1.1.33. So I did and then I restarted setup.exe, but now it brings me to the unistall prompt of the game, as if I had pes installed yet!
To remove it, I oreviously used the "remove wine apps" tool, but after that the game

vector of NA indices
I have a vector Pes with 600 elements some of which are NA's. How can I
form a vector of the indices of the NA's.
for(i in 1:600) if(is.na(Pes[i])) print(i)
prints the indices of the NA's but I can't figure out how to put the
results in a vector.
Thank you very much.

Classic fail-safe N
Hi all,
I was conducting a meta-analysis of single proportions(i.e. without a
control group) using the metafor package. When I performed a classic
fail-safe N, I noticed that the result (the number of missing studies that
would bring p-value to the alpha, to be exact)was different than that I got
in Comprehensive Meta-Analysis Version 2.0. I wonder why R and CMA got
different results.

logistic regression with package 'mice'
Dear all, I request your help to solve a problem I've encountered in using
'mice' for multiple imputation.
I want to apply a logistic regression model.
I need to extract information on the fit of the model.
Is there any way to calculate a likelihood ratio or the McFadden-pseudoR2
from the results of the logistic model?
I mean, as it is possible to extract pooled averaging and odds

General direct input problem
Hi
I've noticed that my gamepad doesn't work on all games requiring a native xinput_3.dll to run (bioshock, racedriver, pes...) but it works with certain games like "trackmania"
maybe there's an enhencement needed to get it working
Is there's something to do ?
What is the difference between xinput and direct input ?
There's some optional regedit dinput option :
