Hi, wondering if anyone can shed some light on how RMark deals with dot notation for missing data?
I am running MSORD models with missing data for the 3rd secondary occasion of the second year
and I would like yearly abundance.
When I give the missing occasion a '.' in the .inp and run in RMark,
I get an abundance of 1493 for that year, but the SE is unreasonable large.
However, when I give the missing occasion a '0' in the .inp, fix that occasion to 0 and run in RMark,
I get an abundance of 1565 for that year with SE = 21.
I realise the latter is the best approach, but I would like to explain the difference between the estimates of 1493 and the 1565.
If anyone can explain the difference in their calculation I'd be very grateful!
