Asymptotic perturbation theory
1966In the foregoing chapters we have been concerned almost exclusively with analytic or uniform perturbation theory, in which the continuity in norm of the resolvent in the parameter plays the fundamental role. We shall now go into a study in which the basic notion is the strong continuity of the resolvent.

Theories between theories: Asymptotic limiting intertheoretic relations
Synthese, 1995This paper addresses a relatively common “scientific” (as opposed to philosophical) conception of intertheoretic reduction between physical theories. This is the sense of reduction in which one (typically newer and more refined) theory is said to reduce to another (typically older and “coarser”) theory in the limit as some small parameter tends to zero.

AbstractThis book relies on maximum likelihood (ML) estimation of parameters. Asymptotic theory assumes regularity conditions hold when the ML estimator is consistent. Typically an additional third derivative condition is assumed to ensure that the ML estimator is also asymptotically normally distributed.

Abstract We have derived the standard errors for the estimated parameters in a random coefficient model from the inverse of the information matrix. This approach is justified in a variety of methods by reference to results from asymptotic theory.

Asymptotic Symmetries in Gravitational Theory
Physical Review, 1962It is pointed out that the definition of the inhomogeneous Lorentz group as a symmetry group breaks down in the presence of gravitational fields even when the dynamical effects of gravitational forces are completely negligible. An attempt is made to rederive the Lorentz group as an "asymptotic symmetry group" which leaves invariant the form of the ...

Unit‐Root Asymptotic Theories (II)
1996Abstract This chapter brings together three unrelated topics of asymptotic theories. It presents a mathematical analysis of tests on the case where {Δxt} is i.i.d., possibly with a non-zero mean. It explains the mathematics used for the case where {Δxt} is serially correlated.

Simulated Asymptotic Least Squares Theory [PDF]
, 2000 We develop in this paper a general econometric methodology referred to as the Simulated Asymptotic Least Squares (SALS). It is shown that this approach provides a unifying theory for 'approximation-based' or simulation-based inference methods and nests the Simulated Nonlinear Least Squares (SSNLS), the Simulated Pseudo Maximum Likelihood (SPML), the ...
