Not a big deal, but I guess nevertheless some more internal validity or

Thanks for the report. That error indicates that sy, the return value
from sdc() is NA, which in turn means that we had fewer than 2 valid
observations of depvar. OK, in that case we'll call funcerr with a
message of "Insufficient valid observations".

Thanks, Allin.

Another thing in the GUI: "randfolds" seems to be activated by default, even though for scripting the doc says the opposite. And it seems to me that this is especially weird in time-series datasets, if I understand the option correctly. For time series we want to keep consecutive obs through randfolds=FALSE, right?

cheers
