Suppose we have a dataset on high school students. Amongst the variables in this dataset are measures of cumulative grade point average ("cumgpa"), a dummy variable for gender (female=1 if the student is female, 0 otherwise), and a dummy variable for race (white=1 if the student is white, 0 otherwise).
We execute a few basic regressions for the dependent variable cumgpa and produce the following output in STATA:
.//Model 1 (coefficients only)
. regress cumgpa white if female==0
------------------------------------------------------------------------------
cumgpa | Coef. Std. Err. t P>|t| [95% Conf. Interval]
-------------+----------------------------------------------------------------
white | .1765394 .0592231 2.98 0.003 .060172 .2929067
_cons | 2.17771 .0505773 43.06 0.000 2.078331 2.277089
------------------------------------------------------------------------------
. //Model 2 (coefficients only)
. regress cumgpa white if female==1
------------------------------------------------------------------------------
cumgpa | Coef. Std. Err. t P>|t| [95% Conf. Interval]
-------------+----------------------------------------------------------------
white | .4949671 .1165576 4.25 0.000 .2646478 .7252865
_cons | 2.30963 .1056241 21.87 0.000 2.100915 2.518344
------------------------------------------------------------------------------
. //Model 3 (coefficients only)
. gen fem_white=female*white
. regress cumgpa female white fem_white
------------------------------------------------------------------------------
cumgpa | Coef. Std. Err. t P>|t| [95% Conf. Interval]
-------------+----------------------------------------------------------------
female | bbbbbbbb .1208802
white | aaaaaaaa .0585118
fem_white | cccccccc .1348207
_cons | dddddddd .0499699
------------------------------------------------------------------------------
Model 3 includes the variable Female and an interaction of Female and White (Fem_White). Some of the STATA output has been concealed. These values can be deduced from Models 1,2.
What is the value of the term cccccccc?
