Hi,
I would like to evaluate the frequency of the variables within the best
selected model by AIC among a set of 12 competing models (I fit them with GLM)
with a bootstrap procedure to get unbiased results. So I would ike to do the
ranking of the 12-model-set 10'000 times separately and
coefficients (order of CV=SE/coefficient).
Any hint for me?
Cheers

Hi,
Fitting all possible models (GLM) with 10 predictors will result in loads of
(2^10 - 1) models. I want to do that in order to get the importance of
variables (having an unbalanced variable design) by summing the up the
AIC-weights of models including the same variable, for every variable
Hello
Instead of testing against 0 i would like to test regression slopes against -1.
Any idea if there's an R script (package?) available.
Thanks for any hint.
Cheers

hi
i have a dataframe a which looks like:
column1, column2, column3
10,12, 0
NA, 0,1
12,NA,50
i want to replace all values in column1 to column3 which do not contain NA
with values of vector b (100,200,300).
any idea i can do it?
i appreciate any hint
regards

Hello
I want to repeatedly extract coefficients and standard errors from a GLM and
write them into a file (1row=all coefficients of model A, 2 row=all
coefficients of model B, etc.). I can extract coefficients but not standard
errors. furthermore I fail to write extracted values line by line
Hello
I want to batch job the calculation of many GLM-models, extract some values and
store them in a file. Almost everything in the script below works (read file,
extract values and write them to file) except I fail in indexing the GLM with
the modelstructure it should run. Running GLM's
