areg y1 x1 x2 if con ==1, absorb(hhno) cluster(hhno)
predict conhat if con ==1, xbd
areg y2 x1 x2 if con ==0, absorb(hhno) cluster(hhno)
predict wconhat if con ==0, xbd
y1 and y2 are dependent variables and xs are independent variables.
I want to test if there is mean difference between the two predicted values
uisng simple 'ttest'.
My question is, do I need to correct standard errors(se) of the 'ttest'
since the observed ys are not independent. If the answer is yes, would you
please suggest me how i can correct it or any other altenative test that can
adjust se.
Many thanks
Dawit
