In the "Generalizations" section, I am missing pairwise/k-wise independence mentioned (i.e. any pair/k-tuple in the sequence is independent, but larger subsets are not necessarily independent). Pairwise/k-wise independence is used in theoretical CS. --David Pal

== IID consistency ==

After noticing the lead contained a mixture of both, I made a bold edit in favour of IID which I personally find less visually distracting than the dots in i.i.d. when the term is dropped into every second sentence. However, IID is not exactly beautiful, either, and typographically I would advise {{sc2|IID}} (i.e. <ttcode><nowiki>{{sc2|IID}}</nowiki></ttcode>), except that this is apparently discouraged in the MOS. This article might the one where it makes sense to go against the recommended-style grain, though it's above my pay grade to decide this unilaterally. &mdash; [[user:MaxEnt|MaxEnt]] 00:57, 20 March 2017 (UTC)

:Your decision has my support, since dropping the [[full stops]] (or ''periods'') from [[initialism]]s (and other [[abbreviations]]) has been throughout the last century or more, and continues to be, a productive process in English writing, as seen in the following usages, for example:

I fully agree with @Undsoweiter. There is no reason for explicitly mentioning machine learning. Moreover, I also do not understand the first reason at the end. Why is the cental limit theorem of any relevance at this point? One is not adding together random variables during likelihood optimization.

== Degraded quality of article due to edits since November 2021 ==

While I understand the value of having students edit Wikipedia articles for a class, numerous issues have been introduced into the article. These include: the use of the pronoun "we"; the inconsistent math fonts for independence of events (which also has other issues); the machine learning section as detailed above in a separate comment; the elimination of important examples illustrating how the i.i.d. sampling can be a flawed assumption; the unnecessary mentioning of "data mining" and "signal processing"; etc. With the semester already finished, it is doubtful the issues will be remedied by members of the class. I think all edits since November 2021 should be undone.
