Variable Selection

Model-Based Clustering and Classification for Data Science, 2019
In our discussion of regression to date we have assumed that all the explanatory variables included in the model are chosen in advance. However, in many situations the set of explanatory variables to be included is not predetermined and selecting them ...

On Perturbation and Variation Methods

Proceedings of the Physical Society. Section A, 1953
It is pointed out that the notation of the theory of functionals and the theorem in it analogous to Taylor's theorem facilitates a compact discussion of perturbation and variation methods in quantum mechanics, both for bound state and scattering problems.

A general numerical algorithm for nonlinear differential equations by the variational iteration method

, 2020
The purpose of this paper is to suggest a general numerical algorithm for nonlinear problems by the variational iteration method (VIM).,Firstly, the Laplace transform technique is used to reconstruct the variational iteration algorithm-II.
