Without such detailed information, raking comes as a rescue since it requires only the knowledge of marginal distributions of selected variables. Popular as it may be, raking takes no account of associations among post-stratifying variables. Furthermore, it relies heavily on Chi-squared tests and a pre-selected p-value (usually 0.5) as the stopping rule of iteration, an ad hoc rule justified only by convenience.

因此，目前最常采用的是「反覆多重加权」的方式，但「反覆多重加权」实际执行时，最大的问题在於其检定方式是透过卡方检定，通常只要其检定P值大於0.5，就认定样本与母群一致，而未考虑一个最佳化的加权值。
