<> " I don't know why -findit- didn't work for Eric, because it does for me. It finds some false positives such as -tabmerge-, but that's a known risk." In this sense, it does indeed work. Somehow I thought that -tabm- should be more obviously highlighted in those results, but with the benefit of hindsight, it was possible to -findit-. Anyway, as Nick points out, the onus is on the initial poster to provide this reference "for free"... HTH Martin -----Ursprüngliche Nachricht----- Von: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] Im Auftrag von Nick Cox Gesendet: Donnerstag, 29. Oktober 2009 14:04 An: statalist@hsphsun2.harvard.edu Betreff: RE: AW: st: AW: tabm with %'s As Martin points out, list members are asked to spell out where user-written software they refer to comes from. This is not a silly little rule, but advice based on promoting everyone's best interests: 1. People who might answer have a clearer sense of the precise problem. 2. People interested in the general topic might learn about something of use or interest to them. 3. Software writers might be helped to recognise their own children. 4. Questioners increase their chance of a quick, correct and complete solution of their problem. Really, no one loses. And anyone who thinks that the request to provide clear and complete questions is out of order should hire consultants and reach for their credit cards. I don't know why -findit- didn't work for Eric, because it does for me. It finds some false positives such as -tabmerge-, but that's a known risk. -tabm- is indeed a part of -tab_chi- The latest public version of -tab_chi- is on SSC. An earlier version is on the StataCorp website. Now to the question: As Eric states, and contrary to Beth's statement, -tabm- does support percent calculations. As the help indicates, you can specify -tabulate- options, and so you can get row, column or cell percents. Here is another dopey example: . set obs 10 obs was 0, now 10 . forval i = 1/5 { 2. gen foo`i' = round(rnormal()) 3. } . tabm foo*, trans col +-------------------+ | Key | |-------------------| | frequency | | column percentage | +-------------------+ | Variable Values | foo1 foo2 foo3 foo4 foo5 | Total -----------+-------------------------------------------------------+---- ------ -2 | 2 1 0 0 0 | 3 | 20.00 10.00 0.00 0.00 0.00 | 6.00 -----------+-------------------------------------------------------+---- ------ -1 | 0 3 4 2 2 | 11 | 0.00 30.00 40.00 20.00 20.00 | 22.00 -----------+-------------------------------------------------------+---- ------ 0 | 5 3 2 5 4 | 19 | 50.00 30.00 20.00 50.00 40.00 | 38.00 -----------+-------------------------------------------------------+---- ------ 1 | 1 3 3 3 3 | 13 | 10.00 30.00 30.00 30.00 30.00 | 26.00 -----------+-------------------------------------------------------+---- ------ 2 | 2 0 1 0 1 | 4 | 20.00 0.00 10.00 0.00 10.00 | 8.00 -----------+-------------------------------------------------------+---- ------ Total | 10 10 10 10 10 | 50 | 100.00 100.00 100.00 100.00 100.00 | 100.00 If Beth needs something else, then she should please specify what that is. Nick n.j.cox@durham.ac.uk Eric Booth Hmm....at second glance, looks like its a part of -tab_chi-.
