Linear Regression vs. Multiple Regression Example Consider an analyst who wishes to establish a relationship between the daily change in a company's stock prices and daily changes in trading volume.

Sometimes equations require more than one step to solve them. The process of solving an equation involves isolating the variable so that the letter terms are on one side of the equals sign, and ...

Nonlinear regression is a form of regression analysis in which data is fit to a model and then expressed as a mathematical function. Simple linear regression relates two variables (X and Y) with a ...

New soliton solutions to the NLSE with parabolic nonlinearity are being explored, featuring conservation laws and pulse ...

Rack-and-pinion drives, another type of linear motion device, get no respect. But they are perfectly capable of competing with the other two “stars” and have their own advantages.

A number of finite element discretization techniques based on two (or more) subspaces for nonlinear elliptic partial differential equations (PDEs) is presented. Convergence estimates are derived to ...
