I'm not sure I understand, but if you want to create a single categorical
variable for each case based on 8 years of data and you have a categorical
variable that takes on one of three possible values (possibility=1,2,3) for
each year (year= 1,2,3,4,5,6,7,8), then you could::
collapse (sum) score, by(caseid)
This will give you an 8 digit number (score) for each caseid with each digit
representing the value of possibility for each year. One advatage of this
approach is that the resulting number can be directly interpreted. If you
had more years than you might need to create the score variable as a double.

Hi List users,
I am having a tough time getting my head around this.
I have data on households which goes for 8 years and in each year i can
observe 3 possibilities. Thus a total of 8^3 possible histories exist.
How would I go about creating a variable that classifies the data into
each of these possibilities?
I have 800 households that I need to classify in this form.
