WitrynaA logarithmic transformation is a transformation where every data-value (x) is re-calculated in a logarithmic form (log (x), or more aptly, ln (x)). Logarithms have a lot of unique properties, such as turning multiplicative operations into addition. This aspect of logarithms is so important, as it allows exponential data to be viewed linearly ...
