Re: st: Propensity Score Matching Between 3 Groups - Stata

Inverse probability weighting is a statistical technique for calculating statistics standardized to a pseudo-population different from that in which the data was collected. Study designs with a disparate sampling population and population of target inference (target population) are common in application. There may be prohibitive factors barring researchers from directly sampling from the target population such as cost, time, or ethical concerns. A solution to this problem is to use … WebConvert P S P S to I P W I P W = A P S + 1−A 1−P S A P S + 1 − A 1 − P S Convert PS to IPW using the formula.
