On #2, note that the manuals are bundled with Stata 11. If you are using some previous version, you should indicate what it is. Nick n.j.cox@durham.ac.uk Tunga Kantarci 1. The regression output presents ANOVA analysis. Take for example, the MS column for the residuals, which is the mean of the sum of squared residuals. I would like to calculate a quantity using the "nlcom" command and in this command I would like to indicate the estimated MS residual. What is the command for calling the MS residual in, for example the nlcom command? Put more simply, we call for example a coefficient estimate of a variable with "_b[variablename]". What I am asking is how do I call a figure from the ANOVA table? For example the MS of residuals? I could just use the estimated figure for MS residuals but this is not what I want. 2. Suppose that I wish to calculate the standard error of _b[_cons]/_b[variablename]. Stata help system indicates that Stata uses the "delta" method to calculate this standard error. But I wish to see what Stata exactly calculates. How do I see it? Or do I need the Stata manual books for this? Stata help system does not indicate any formula it uses. * * 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/
