All sorts of non-linear functions of the explanatory variables can be fit by the model.

Generally, the numerically generated seismic data are non-linear functions of the earth model parameters.

Additionally, negative values of R may occur when fitting non-linear functions to data.

If a non-linear function is available and thought useful such functions can be substituted for the functions used here.

The original form assumed a strictly linear structure, but this assumption can be weakened to allow for non-linear functions.

It is a typical example of non-linear multimodal function.

The following properties are known to hold for the escaping set of any non-constant and non-linear entire function.

This process essentially linearizes the non-linear function around the current estimate.

For non-linear functions, the rate of change varies along the curve.

More generally, condition numbers can be defined for non-linear functions in several variables.
