A Validation Study for Using Iterative Proportional Fitting to Weight the Traumatic Brain Injury Model Systems National Database: An NIDRR-Sponsored Study

In general, IPF aligns population estimates on the basis of weighted Traumatic Brian Injury Model Systems data and known population parameters. It is reasonable to assume that IPF has the same effect on unknown variables. This provides confidence to researchers wishing to use IPF for making population projections in analyses.
