When performing a linear fit of y against x, for example, an appropriate transformation x’ (of the variable x), y’ (of the variable y), or both, can often significantly improve the correlation. A residual plot can reveal whether a data set follows a random pattern, or if a nonlinear relationship can be detected.
The probability characteristics of the envelope, random phase, and instantaneous frequency of narrow-band random processes are presented which are required for the analysis of the operation of various radio-frequency devices. Attention is given to quasi-static, linearization, markovian, and functional-series methods for the analysis of transformations of random processes by inertial systems.
I was studying bishop machine learning and pattern recognition and on page 18, it says under nonlinear change of variable, a pdf transforms differently from a normal function. I think it will also change differently for a linear transformation.

By transformation we simply mean functions of x, and any function of a random variable (or set of random variables) is itself a random.
Moreover, this type of transformation leads to simple applications of the change of variable theorems. Suppose first that \(x\) is a random variable taking values in an interval \(s \subseteq \r\) and that \(x\) has a continuous distribution on \(s\) with probability density function \(f\).
The transformations that give us the features in the new data-space are just functions of the input features. But it requires non-linear transformation to produce a non-linear model in the original data-space.

The nonlinearity between the inputs and the outputs of a transformation can be of two types: (1) the cases in which the structural system is linear and the loads are nonlinear expressions of known random variables; (2) the cases in which the structural system is governed by an equilibrium equation that is a nonlinear expression of the response.
So we have some data here that we can plot on a scatter plot that looks something like that and so the next question given that we've been talking a lot about lines of regression or regression lines is can we fit a regression line to this well if we try to we might get something that looks like this or maybe something that looks like this i'm just eyeballing it obviously we could input it into.

Nonlinear transformations of random processes abstract: this paper provides a general method of calculating the mean-square bandwidth (and other spectral moments) of an arbitrary zero-memory nonlinear transformation of a stationary random process. The method is valid when the original process is an arbitrary combination of other random processes.
