Webb28 apr. 2024 · Raking, also known as iterative proportional fitting (IPF), is a method for adjusting sample weights so that they more accurately reflect the true population weights. The goal of raking is to adjust the sample weights so that the row and column totals (also known as the marginals) mimic those of the population.
