psacalc R_max estimation

[Mukesh Punia]

Dear users,

I am using psacalc to test OVB

My regression equation is-

 reg y x1 x2 x3 x4 x5 x6 x7 cid* agedum*

Then I use psacalc

 psacalc beta x1, delta(1)rmax(.23) control(x2 x3 cid* agedum*) // this results as given in figure-1

 psacalc delta x1, rmax(.23) control(x2 x3 cid* agedum*) // this results as given in figure-2

From these figures, I get Baseline Effect, Controlled Effect, Identified Set, and ̃ δ for β = 0 given R_max

My query is --

How to get Max. R for β = 0̃ given δ = 1?
