RE: st: how to make xi dummies inherit labels |

What I was really after in the end was similar to the output of e.g.

. xi: logistic y i.x

. reformat, eform

- but with the coefficients labelled using the value labels assigned to x.

-desmat- does achieve this, but I had a couple of different problems when I tried -desmat-:

1) It takes over 2 minutes to run the first univariable logistic regression with -desmat- on my data , when -xi- is seemingly instant. May be connected to the fact that my dataset has 1100 variables (and 2400 observations). Much quicker subsequently though, even run on different variables.

2) I can't see how to get -desmat- to exponentiate the coefficients (to give odds ratios with logistic regression) when used as a command prefix:

. desmat: logistic y i.x

gives the same output as:

. desmat: logit y i.x

- and there's no -eform- option as there is with -outreg- and -reformat-.

Also I think -reformat- or -outreg- give me more flexibility in deciding what I want in the output, so I don't need to do so much work on the output before I present it to my client, which is ultimately my aim.

In conclusion i'll probably use Nick's 'canned solution' for transferring value labels to variable labels of dummies, in combination with -reformat- or -outreg-. But maybe it would be nice if there was an option for -xi- to tell it to inherit the labels in this way. Put that on the wish list for Stata 8...
