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 … nothing to hide ending explained

Webfor the probability that an individual is a complete case given a set of predictors of missingness. The analysis model is then ﬁtted to just the complete cases, inversely weighting each by its estimated probability of being complete given its missingness predictors. A drawback of IPW is that it can be very inefﬁcient, because, like http://www.columbia.edu/~md3405/BE_Risk_3_17.pdf WebInverse probability weighting (IPW) is purported to reduce this bias.
