Like other eclass commands, -mlogit- stores results in -e()-. After fitting a model, type -ereturn list- to see what's available. For example, mat li e(b) returns a vector with the estimated coefficients. You can then use/rearrange these results to your liking. For example, the following code creates a 2 x k matrix with coefficients, with k being the number of predictors in the model (including constants): *--------------------------------------- // Toy data clear sysuse auto replace rep78 = rep78 - 2 if rep78 > 2 // -mlogit- fit mlogit rep78 price mpg headroom trunk, b(1) // Create a 2 x k matrix, where k is the // number of predictors in the model, // for an arbitrary number of predictors qui levelsof `e(depvar)', loc(level) loc base = e(baseout) loc rowlab = regexr("`level'","`base'","") loc np = e(k) mat b = e(b) mat b1 = b[1, `=`np'/2+1'..`np'] mat b2 = b[1, `=`np'+1'..`=`np'+`np'/2'] mat bmat = b1\b2 mat rownames bmat = `rowlab' mat li bmat *--------------------------------------- This could further be automated, for example to allow for arbitrary base outcomes and number of outcome categories.
