In Verrill and Johnson [2007. Confidence bounds and hypothesis tests for normal distribution coefficients of variation. USDA Forest Products Laboratory Research Paper FPL-RP-638], we use this result to establish that estimators based on Newton steps from [square root]n- consistent estimators may be used in place of efficient solutions of the likelihood equations in likelihood ratio, Wald, and Rao tests. Taking a quadratic mean differentiability approach rather than our Crame´r condition approach, Lehmann and Romano [2005. Testing Statistical Hypotheses, third ed. Springer, New York] have outlined proofs of similar results. However, their Newton step estimator results actually rely on unstated assumptions about Cramer conditions. Here we make our Cramer condition assumptions and their use explicit.https://www.fpl.fs.fed.us/documnts/pdf2007/fpl_2007_verrill001.pdf147 KBhttps://www.fs.usda.gov/treesearch/pubs/31603316030Statistics & probability letters.
