While linear functions are easy enough to define, the term “nonlinear” takes in everything else. “There’s this famous quote — I’m not sure who said it first — that the theory of ...

Dr. James McCaffrey presents a complete end-to-end demonstration of linear regression using JavaScript. Linear regression is ...

The same thing would be true for the first function above, f(x) = x²: n² would equal n.This would be a weird mathematics indeed (there are algebras in which this happens for some nonunit ...

Non-linear physics is the study of systems where the output is not directly proportional to the input. Unlike linear systems, which follow simple, predictable relationships, non-linear systems exhibit ...

Using nonlinear Kalman filtering to estimate signals. It appears that no particular approximate [nonlinear] filter is consistently better than any other, though . . . any nonlinear filter is better ...

We demonstrate the implementation of a variety of non-linear models that are more appropriate for modeling plant growth than are the ... A bestiary of non-linear functions for growth analysis.
