There are many more variables involved in | that specific example, such as time since last negative | feedback, total age of account, feedback over the last 90 days, | etc. | DaiPlusPlus wrote: | Sometimes that's necessary - a lot of Bayesian- _stuff_ is very | counter-intuitive. | frakt0x90 wrote: | If anyone wants to get more into Bayesian stats, I will always | recommend Statistical Rethinking by Richard McElreath.
