Strange behavior with poisosn and glm
...data:
y v1 month
2 1 january
3 1.4 februrary
1.5 6.3 february
1.2 4.5 january
5.5 4.0 march
I use this call:
m <- glm(y ~ v1 + month, family="poisson")
R gives me back a model with variables of
Intercept
v1
monthJanuary
monthFebruary
monthMarch
I'm concerned that this might be doing some strange things to my model.
Can anyone offer some enlightenment?
Thanks!
