Similarly, it is possible to reduce the magnitude of raw data counts by replacing their absolute values with logarithms.
A peculiar feature of the logarithmic transformation is precisely that of reducing the relevance of greater values, and, at the same time, of amplifying smaller values, thereby achieving greater uniformity of value distribution.
In addition to logarithms, it is possible to use other power functions, which allow the stabilization of the variance of a data distribution (such as the Box–Cox transformation).
