Re: st: Confidence Interval for Standardized Coefficients

Hi,
SPSS can apparently produce the Meyer and Younger (1976) confidence
interval for standardized coefficients in linear regression. Can Stata
produce anything equivalent?
I'm not familiar with Meyer and Younger. But, my guess is that you
could standardize the variables yourself and then run the
regression. In this example I use Ben Jann's -center- command,
available from SSC.
. webuse auto, clear
(1978 Automobile Data)
. quietly reg price weight foreign
. center price weight foreign if e(sample), s
. reg c_price c_weight c_foreign
