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 … http://www.spss-asp.com/software/statistics/statistics-server/

So far we have discussed the use of IPTW to account for confounders present at baseline. In longitudinal studies, however, exposures, confounders and outcomes are measured repeatedly in patients over time and estimating the effect of a time-updated (cumulative) exposure on an outcome of interest requires … See more We will illustrate the use of IPTW using a hypothetical example from nephrology.
