Knowledgeable useRs,
Please, advise how to use offset with a factor. I estimate monthly effects from
a much bigger data set as monthly effects seem to be stable, and other
variables are estimated from a small, but recent data set as there is variation
in those non-seasonal coefficients.
How can I use the seasonality estimates from the big data set as an offset
provided to the small data set. I know an offset is supposed to be
quantitative, but this is such a practical and sensible scenario, I feel
compelled. Assume I have 11 coefs estimated with contr.sum.
Thanks everybody
Stephen
