Tancks Maarten L. Buis,
I Follow the reference "Sensitivity analysis for
average treatment effects". But the results of my analysis are a bit
confusing. you Could help with this?
Example
. mhbounds _tx86_96, gamma(1 (0.25) 4)
Mantel-Haenszel (1959) bounds for variable _tx86_96
Gamma Q_mh+ Q_mh- p_mh+ p_mh-
-------------------------------------------------
1 . . . .
1.25 -741455 . 1 .
1.5 . . . .
1.75 -908093 . 1 .
2 -1.0e+06 . 1 .
2.25 . -1.6e+06 . 1
2.5 -1.3e+06 . 1 .
2.75 -980853 . 1 .
3 -663178 . 1 .
3.25 -642119 -2.5e+06 1 1
3.5 -1.7e+06 . 1 .
3.75 . . . .
4 . . . .
Gamma : odds of differential assignment due to unobserved factors
Q_mh+ : Mantel-Haenszel statistic (assumption: overestimation of
treatment effect)
Q_mh- : Mantel-Haenszel statistic (assumption: underestimation of
treatment effect)
p_mh+ : significance level (assumption: overestimation of treatment effect)
p_mh- : significance level (assumption: underestimation of treatment effect)
