stepAICc function (based on MASS:::stepAIC.default)
...for model selection.
The code is appended below. Somehow the calculations are still not correct and I would be grateful if anyone could have a look at what might be wrong
with this code...
Here is a working example:
##
require(nlme)
model1=lme(distance ~ age + Sex, data = Orthodont, random =~1)
stepAICc.Christoph(model1)
##
this gives the correct initial AICc value, but wrong values inside the stepAICc (and probably dropterm.AICc) function. All three functions are
appended below.
Many thanks and best wishes,
Christoph

stepAICc
Dear R users,
Would it be difficult to change the code of stepAIC (from the MASS
library) to use AICc instead of AIC?
It would be great to know of someone has tried this already.
Best wishes
Christoph.
