Greetings List,
I am completing an analysis of GPA against several high school grade
variables. I have regressed the GPA on the three high school grade variables,
and calculated and stored the residuals from this regression.
My output looks like this so far:
regress gpa hsm hss hse
Source | SS df MS Number of obs = 224
-------------+------------------------------ F( 3, 220) = 18.86
Model | 27.7123302 3 9.23744341 Prob > F = 0.0000
Residual | 107.750459 220 .489774812 R-squared = 0.2046
-------------+------------------------------ Adj R-squared = 0.1937
Total | 135.462789 223 .607456452 Root MSE = .69984
------------------------------------------------------------------------------
gpa | Coef. Std. Err. t P>|t| [95% Conf. Interval]

hsm | .1685666 .0354921 4.75 0.000 .0986185 .2385147
hss | .0343156 .0375589 0.91 0.362 -.0397057 .1083368
hse | .0451018 .0386959 1.17 0.245 -.0311602 .1213638
_cons | .5898766 .2942432 2.00 0.046 .0099804 1.169773

. predict yhat
(option xb assumed; fitted values)
. predict resid, residuals
Now, I am new to stata, just started learning about it this semester. And I am
trying to plut the residuals versus each of the three high school grade
variables and versus the predicted value of GPA. How do I do this? Also, does
stata have a command to obtain the fitted regression equation>?
