Linear and nonlinear models are two types of mathematical functions that can be used to describe the relationships between variables. In this article, you will learn what they are, how they differ ...

However this is not the case with non-linear functions. A non-linear function does not have a constant slope. Consider the non-linear function shown below. What is the slope at some point such as P?

Often in economics a linear function cannot explain the relationship between variables. In such cases a non-linear function must be used. Non-linear means the graph is not a straight line. The graph ...

Linear and nonlinear programming are two types of optimization methods that can help you find the best solution to a problem involving decision variables, constraints, and an objective function.

To approximate functions of a single variable by using linear interpolation is routine in empirical studies. Here, we consider approximating functions of several variables in a similar piecewise ...

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 ...
