Re: st: R: Data =?UTF-8?B?Q29ycnVwdGlvbj8=?=
Me too
It gives the same results as Carlo in Stata 9.2 and Stata 10 all under Linux:
. summ oil_level gdp
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
oil_level | 40 781.27 93.45438 548.9 948.7
gdp | 40 24624.7 6083.752 15492.84 36098.15
Good Luck
