Hi everybody, are there any built-in collection functions for mean, median, and mode? https://www.dictionary.com/e/average-vs-mean-vs-median-vs-mode/ As I understand, we can use

.average()

in a list of Int which works as mean. But what about the others? In particular

.mode()

(I would prefer just

.mostFrequent()

) would be useful for any type of collection or at least List 🤔

There is a link here for a library called kotlin-statistics, but it 404’s https://kotlinlang.org/docs/data-science-overview.html#kotlin-libraries

median:

list.sorted()[list.length / 2]

(plus whatever logic you want to handle ties) mode:

list.groupingBy { it }.eachCount().entries.maxBy { it.value }.key

Yes I was using that. Will need to continue with it, thanks guys!
