puting mean into a global variable

[Peter Novotny]

Hello Statlisters,

How can I put mean into a global macro variable? The code below produces an empty value instead of 6165.257

webuse auto
summarize price
global mean_price=r(mean)
disp `mean_price'

The global is there; you just used the syntax for displaying a local macro.

. sysuse auto, clear 
(1978 Automobile Data)

. summarize price

    Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
       price |        74    6165.257    2949.496       3291      15906

. global mean_price=r(mean)

. disp `mean_price' 


. disp $mean_price 
6165.2568
