st: STATA 11 MI - how to get a standardized correlation?

Hello -

I am using STATA 11's MI features.  However, as I saw noted on another
post, the "beta" option for mi estimate: reg does not work (that post
is here:
 I would like to estimate the standardized correlations among some of
my imputed variables.  Does anyone know how to do this easily?  I've
used the following round-about procedure but I'm not sure that it is
correct (and whether correct or not, it is annoying) -

mi estimate: mean y x
(using the SE produced from the above step, I calculate the standard
deviation by hand)

/****Then, I standardize the variables of interest*****
mi passive: generate x2=(x-mean_of_x)/STD_of_x
mi passive: generate y2=(y-mean_of_y)/STD_of_y

/*****regress the standardized x on standardized y***/
mi estimate, post: reg y2 x2

Thanks for any and all help/suggestions!
