WebRobbins and Monro (1951) introduce the first stochastic approximation method to address the problem of finding the root of a regression function M (x). Precisely, let Y =Y (x) denote a random outcome of interest at the stimulus level x with expectation E (Y ) = M (x). The objective is to sequentially approach the root x∗ of the equation clock time table

WebWhile standard stochastic approximations are subsumed by the framework of Robbins and Monro (1951), there is no such framework for stochastic approximations with proximal updates. In this paper, we conceptualize a proximal version of the classical Robbins-Monro procedure. Our theoretical analysis demonstrates that the proposed procedure has ...

The Robbins–Monro algorithm, introduced in 1951 by Herbert Robbins and Sutton Monro, presented a methodology for solving a root finding problem, where the function is represented as an expected value. Assume that we have a function , and a constant , such that the equation has a unique root at . It is assumed that while we cannot directly observe the function , we can instead obtain measurements of the random variable where . The structure of the algorithm is to then gen… WebThe Robbins-Monro procedure (1951) for stochastic root-ﬁnding is a nonparametric ap-proach. Wu (1985, 1986) has shown that the convergence of the sequential procedure can be greatly improved if we know the distribution of the response. Wu’s approach assumes a parametric model and therefore its convergence rate slows down when the assumed ...

Because we are dealing with discrete dose levels, it is difficult to apply Wu's argument, especially when there is model misspecification. One will see in the following that there are situations when consistency is not obtained.
