Yes I totally admit my confusing line by defining time periods as time

the data.

This is not my strong area, but I think the key thing is that you need two or more of something; it doesn't need to be time periods, it could, for example, be siblings. As far as I can tell, the -clogit- command is pretty much the same as -xtlogit, fe- and yet the manual's examples given for -clogit- are very different than the examples for -xtlogit, fe- .
