Web20 de mai. de 2024 · In some cases, this can be corrected by transforming the data via calculating the square root of the observations. Alternately, the distribution may be exponential, but may look normal if the observations are transformed by taking the natural logarithm of the values. Data with this distribution is called log-normal. WebFor example, if you had say $70\%$ of the distribution at $1$, $20\%$ at $2$ and the rest spread across higher values, then no matter which monotonic transformation you apply*, the two lowest values would still have $70\%$ and $20\%$ of the values respectively. Squashing up the $10\%$ that's in the far right tail just won't help much.
