The U.S. Department of Commerce welcomes comments on alternatives to the Cohen's d test in antidumping investigations.

The U.S. Department of Commerce (DOC) is seeking comments from interested parties on an alternative to the Cohen's d test in antidumping investigations to satisfy the requirement of section 777A(d)(1)(B)(i) of the Tariff Act of 1930, as amended, to determine whether "there is a pattern of export prices (or constructed export prices) for like merchandise that varies significantly among specific buyers, regions, or time periods."

Bộ Công thương•23/05/2025

The Cohen's d test has been used by DOC in antidumping investigations for more than 10 years. However, recently, the Court of Appeals for the Federal Circuit ruled that DOC's use of this test was unreasonable because it was not based on a large enough database and did not satisfy the statistical assumptions of normal distribution and equal variance. Therefore, DOC organized a public comment period on the alternative to the use of the above Cohen's d test.
