When using WIDETOLONG, is it possible to store the time variable "REPETITION = time" (e.g. as 1, 2, 3) so that I additionally control for measurement occasion when analyzing the data as a multilevel model? How is this achieved?
I tried adding it to AUXILIARY but I get "unknown variable(s) in the AUXILIARY option: TIME"
