glm or transformation of the response?
Dear all,
For an introductory course on glm?s I would like to create an example to show the difference between
glm and transformation of the response. For this, I tried to create a dataset where the variance
increases with the mean (as is the case in many ecological datasets):
poissondata=data.frame(
response=rpois(40,1:40),
explanatory=1:40)
attach(poissondata)
However, I have run into

Understanding linear contrasts in Anova using R
#I am trying to understand how R fits models for contrasts in a
#simple one-way anova. This is an example, I am not stupid enough to want
#to simultaneously apply all of these contrasts to real data. With a few
#exceptions, the tests that I would compute by hand (or by other software)
#will give the same t or F statistics. It is the contrast estimates that
R produces

How do I compare 47 GLM models with 1 to 5 interactions and unique combinations?
Hi R-listers,
I have developed 47 GLM models with different combinations of interactions
from 1 variable to 5 variables. I have manually made each model separately
and put them into individual tables (organized by the number of variables)
showing the AIC score. I want to compare all of these models.
1) What is the best way to compare various models with unique combinations
and different number

I am trying to create a frequency distribution and I am a bit confused.
Here are the commands I have entered:
