If anyone has a text that addresses the possibility of empty strata, please comment. As defined right now a stratum can't be empty. I'm not going to have access to stat books for around a week, I'll look into it then if it's not resolved before. --GFauxPas (talk) 14:15, 13 September 2012 (UTC)

I think that the definition of partition disallows the strata to be empty. --Lord_Farin (talk) 15:11, 13 September 2012 (UTC)
Right. But a stratum might be able to be empty, in which case the definition I've created here needs to be altered to carry that possibility. I.e, a stratum might be defined as a component or an empty set. --GFauxPas (talk) 17:45, 13 September 2012 (UTC)
