<> Vectors are not really a well-known concept in Stata, although naturally you can have them in -mata-. I have never missed them, though, as you can do what you want to do without them most of the time. What is it you want to achieve? *** clear* input byte( a b c) 3 4 3 2 3 4 2 5 6 2 0 4 end compress list, noobs capt which tomata if _rc ssc inst tomata tomata a b c mata A=a,b,c A[2,.]*A[2,.]' A[2,.]'*A[2,.] end *** HTH Martin -----Ursprüngliche Nachricht----- Von: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] Im Auftrag von Steven Ho Gesendet: Donnerstag, 15.

Suppose I have a data like this: a b c 3 4 3 2 3 4 2 5 6 2 0 4 What I want is something like this, of course the following command doesn't work gen arrayZ[_n]=( a[_n], b[_n], c[_n]) so that arrayZ[3] for example would be (2,5,6) ie. when I invoke Z[t] it will give me a VECTOR of t-th row I need this because I will do a whole bunch of operations to Z[t]Z[t]' How to achieve this? * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
