This article compares different methods for equivalence testing of aerodynamic particle size distributions, with a focus on the modified chi-square ratio statistic.

This article fosters understanding about the proposed stepwise cascade impactor equivalence test, including the PBE test and the mCSRS. The PBE test is compared with the ABE test and the outcome of the stepwise cascade impactor equivalence test is compared with performing statistical tests on individual stages.
