Oct 10, 2020 · The Log Transformation is used to transform skewed datasets to achieve linearity (near-normal distribution) by comparing log (x) vs. y.

A logarithmic transformation, or log transform, applies the natural log (ln) to a variable in your dataset. It changes the scale of the data by compressing large values more than small ones.

Log transformations are often recommended for skewed data, such as monetary measures or certain biological and demographic measures. Log transforming data usually has the effect of spreading out …
