Saving QUAIDS elasticites as separate variables

[Mariko Wijekoon]

Hi Statalisters

I am trying to save the elasticities that are generated by Brian Poi (2012) "quaids" command as separate variables.

To be specific, I want the elasticites in the price elasticities matrix to be saved as unique variables such as row 1, column 1 elasticity as one variable and row 1 column 2 as another variable etc.

Saving the variables in the following way, gives me unique columns only so that I have 4 separate variables (col1 col2 col3 and col4) but not 16 separate variables which I want.
Any suggestions?

Thank you in advance

What about

estat compensated, atmeans
mat pricec =r(compelas)
mat pricecv=vec(pricec)'
svmat double pricecv

It worked! Thank you very much Jorge!!!

Dear Mariko,
I am trying to estimate a censored demand system using quaids and was wondering if you could share the program codes you used with any supporting documentation. I understand it worked for you after some debugging and would appreciate your assistance.

A small tip is that you can look at people's profiles to see when they were last active. In this case Mariko was last active on 05 Nov 2014, so a personal response would probably require writing directly, although there is no guarantee that people's email addresses are identifiable.
