st: RE: create local from element of matrix e(b) |

I know of a two-line solution mat b = e(b) local bw = b[1,1] and I too would be interested to hear of a shorter one. Nick n.j.cox@durham.ac.uk Claire Kamp Dush I am sure someone had to have asked this type of question before, but in my googling and searching of the statalist archive, I could not come across a clear answer. I am trying to create a local that equals an element of matrix e(b) produced by Stata following xtreg, fe. In fact, I am trying to get the first element. Here is what I did: quietly xtreg mdepc wavedi mdis_coh, fe . matrix list e(b) e(b)[1,3] wavedi mdis_coh _cons y1 .24873096 .34650713 .83985765 . local dif = el(e(b), 1,1) matrix operators that return matrices not allowed in this context r(509); . local dif = e(b)[1,1] invalid syntax r(198); . gen dif = el(e(b), 1,1) matrix operators that return matrices not allowed in this context r(509); . gen dif = e(b)[1,1] matrix operators that return matrices not allowed in this context r(509); I would appreciate any advice - I am sure I am making a really obvious mistake. * * 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/
