Adrian de la Garza <kokootchke@hotmail.com>: One solution is to make the tab using an estimation command. The coefs and SEs are available after estimation commands as matrices and as scalars (see [U] 13.5 for the latter, and also try -eret list- after any estimation command for the former). Here's a variety of illustrations: sysuse nlsw88, clear tab collgrad ind, row nofr proportion ind, over(coll) mat li e(b) test [Mining]_b[_subpop_1]=[Mining]_b[_subpop_2] g one=1 svyset [pw=one] svy: tab collgrad ind, row se di _b[p24] di _se[p24] test _b[p22]=_b[p12] mat b=e(b) mat b24=b[1,"p24"] mat li b24 mat V=e(V) mat V24=V["p24","p24"] mat li V24 di sqrt(V24[1,1]) [The se option on svy: tab is not optional; if you leave it off, the e() results will contain cell proportions instead.] The matrices and _b and _se variables work the same way after regression or other estimation commands.

For example, suppose I want to create a variable x equal to the value contained in cell (2,1), x = 73.53. How can I do this? > > (b) Now, is there a way to save the whole table above to a matrix?

Can I save the stuff in the regression output to other variables? For instance, if I want the estimate and the standard errors of the coefficient of var3, and I want to put them in a scalar x1 and x2, respectively, how do I do this? * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
