Dr. King,
I attempted to use your Amelia program on a data matrix with all
variables being nominal (and set as such in the "Other Options" screen).
Upon trying to analyze the data, Amelia exited with the following error:
C:\GAUSS\SRC\SORTMC.SRC(89) : error G0057 : Procedure stack overflow -
expression too complex
Currently active call: SORTMC [89]
I've attached the log file as well as the data matrix I was trying to
analyze.
Any help would be greatly appreciated.
Cheers,
Jack Newton
You have around 3000 observations, a very large fraction of which is
missing. Although you have only 8 columns of data, declaring them all
nominal means that Amelia will create a very large number of variables
from these (one less than the number of categories for each variable).
This is probably more than can be handled by a big margin. Maybe you can
find some other (continuous) variables to add to your dataset?
Note also the Amelia Listserv, which I'm ccing and you can subscribe to at
my web page. Best of luck.
