Hello, I would like to ask two unrelated questions. 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. Thank you in advance. * * 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/
