Hi
i am running a glm model family Gamma(link=log) trying to predict a
vector
of 1554 (real) values
Using predict() i got a vector of 950 predicted values instead of
1554.
The predictions are good though
The model doesnt take account of negative values and NAs which are
only 121
values.
Taking the logs of negative numbers?
Any clue?
I see a couple of possibilities.
