Okay, understood. cl(idcode hours) obviously won't work.

Hi, Sascha,OK, take the stata example from the link as an example, if what Iwant toreplicate using the stacking process is: est clear sysuse nlsw88, clear reg wage hours if south est sto south reg wage hours if smsa est sto smsa suest south smsa, cluster(hours)How to realize clustering on "hours" in the stacking process? justuse "regwage hours? n, cl(hours)" ? But I think we also need to cluster on"idcode"to make the stacking process equivalent to the -suest- command. Sowhatshould I do to use the stacking process to get the outcome of "suestsouthsmsa, cluster(hours)"? Many thanks, Sharon Re: test of the equality of coefficients in two models Aug 17, 2010; 04:07am — by Sascha Heller Maybe I don't understand your question exactly, but for the STATA example (given in the link), it work's fine when clustering for any other variable (hours etc.) and the SEs change. Does that answer your question? If not, please give further info.
