# Linear versus non-linear transformations

- ## Linear transformation

- F(x) of a raw data vector x such that F is a linear function of x. E.g. F(x)=2x+1

- ## Non-linear transformations

- F(x) of a raw data vector x such that F is a non-linear function of x. E.g. F(x)=1(1+e-x.c)

- ## Other non-linear transformations

- The logarithmic function, F(x)=log10x.
