The **reciprocal transformation** is defined as the transformation of x to 1/x. The transformation has a dramatic effect on the shape of the distribution, reversing the order of values with the same sign. The transformation can only be used for non-zero values.

A negative reciprocal transformation is almost identical, except that x maps to -1/x and preserves the order of variables.
