§2.3(ii) Watson’s Lemma
… ►(In other words, differentiation of (2.3.8) with respect to the parameter (or ) is legitimate.) … ►Watson’s lemma can be regarded as a special case of this result. ►For error bounds for Watson’s lemma and Laplace’s method see Boyd (1993) and Olver (1997b, Chapter 3). … ►The first result is the analog of Watson’s lemma (§2.3(ii)). …15: 2.6 Distributional Methods
