Power law indicates an exponential distribution, which is often taught right after normal distribution in most probability classes. Normal distribution usually considered as white noise, hence a fixed value + white noise is often Normal, which is quite common as well.
- alimw 9y ago> Power law indicates an exponential distribution This sounds wrong. One is invariant under scaling, the other under translation.
- srean 9y ago> This sounds wrong. It is. However there is a way to make it correct. Your second sentence is spot on the intuition. If you log transform power-law distributed random variable the RV that you get is an exponentially distributed RV.
