Subject | Re: st: Factor variables and outreg/outreg2 |
Date | Sun, 4 Apr 2010 16:17:14 +0100 |
Dear all, My aim is to obtain a table only for some coefficients (the interaction terms or factor variables) using -outreg2-, but -outreg2- does not work with factor variables. I found a thread where the same problem was discussed on 28 January 2010, but there is no solution provided. Any suggestion/fix that could be implemented? Please find an example below. Thanks Mirko *-------------- begin example --------------------- sysuse auto, clear tempname myfile regress mpg i.foreign##c.weight i.rep78 headroom outreg2 i.foreign##c.weight headroom using `myfile', see *---------------- end example --------------------- . sysuse auto, clear (1978 Automobile Data) . . tempname myfile . . regress mpg i.foreign##c.weight i.rep78 headroom Source | SS df MS Number of obs = 69 -------------+------------------------------ F( 8, 60) = 22.97 Model | 1764.16138 8 220.520173 Prob > F = 0.0000 Residual | 576.041518 60 9.60069196 R-squared = 0.7538 -------------+------------------------------ Adj R-squared = 0.7210 Total | 2340.2029 68 34.4147485 Root MSE = 3.0985 ------------------------------------------------------------------------------ mpg | Coef.
