Subject: st: storing t value from a t-test
Hi everybody,
Does anyone who knows how can i store the T value of the T Test in a local macro?
Two-sample t test with equal variances
------------------------------------------------------------------------------
Group | Obs Mean Std. Err. Std. Dev. [95% Conf. Interval]
---------+--------------------------------------------------------------------
1 | 77 3.402597 .0872214 .7653644 3.228881 3.576314
2 | 13 3.615385 .2129904 .7679476 3.151318 4.079451
---------+--------------------------------------------------------------------
combined | 90 3.433333 .0806497 .76511 3.273084 3.593583
---------+--------------------------------------------------------------------
diff | -.2127872 .2296004 -.6690697 .2434953
------------------------------------------------------------------------------
diff = mean(1) - mean(2) t = -0.9268
Ho: diff = 0 degrees of freedom = 88
Ha: diff < 0 Ha: diff != 0 Ha: diff > 0
Pr(T < t) = 0.1783 Pr(|T| > |t|) = 0.3566 Pr(T > t) = 0.8217
I would like to store t ( in this case -0.9268) and the p-value (in this case 0.1783)
thank you
