Code:
* Example generated by -dataex-. To install: ssc install dataex clear input float ones int(x2 x3) 1 22 5 1 17 6 1 20 3 1 15 4 1 18 2 1 20 3 1 16 10 1 19 20 1 14 8 1 14 1 end
where xi is a vector.
Kindly, show me every possible steps as I am trying to learn and see how the above expression ends up containing sums of squares and cross products of the regressors. If my dataex is not appropriate, please use whatever seems appropriate. Thanks in advance!
