Web1 day ago · In a tweet just hours after the FBI arrested Massachusetts Air National Guardsman Jack Teixeira, 21, Greene, R-Ga., praised his alleged actions and implied President Joe Biden was "the real enemy." WebInverse probability weighting (IPW) is a commonly used method to correct this bias. It is also used to adjust for unequal sampling fractions in sample surveys. This article is a review of the use of IPW in epidemiological research. We describe how the bias in the complete-case analysis arises and how IPW can remove it.
