An extra method combines the regression adjustment and IPW strategies (teffects ipwra). Listed here we specify each a model for the result as well as a design to the cure assignment system. This approach is so called doubly strong: it gives regular estimates provided no less than one among both of these versions is accurately specified.
The opportunity of bias occurs as the apparent change in final result amongst both of these groups of models could rely on properties that affected whether or not a unit obtained a given treatment in place of due to the effect in the therapy per se. In randomized experiments, the randomization allows impartial estimation of remedy results; for each covariate, randomization indicates that treatment method-groups will probably be well balanced on common, from the law of large quantities.

That is, I envisioned that a single measure of outcome (such as, RR) would generally reject the null when one other measure (threat variance) did.
