I noticed today that we have a tag for without a description. For once, this isn't my fault. I hope that by bringing it to the attention of meta readers, we could create one. (I don't know anything about l-moments.)

    $\begingroup$ It looks like this tag was created by @Kjetilbhalvorsen. He may be able to provide the most appropriate excerpt. $\endgroup$ – gung - Reinstate Monica Jul 14 '16 at 21:13

    $\begingroup$ No problem. This is just about keeping Meta tidy. $\endgroup$ – amoeba Sep 22 '16 at 15:40

Following @gung's comment above, I pinged @Kjetil and asked to provide a wiki excerpt. He kindly agreed, and so here is the new excerpt:

A kind of moments based on linear functions of order statistics. Their interpretation is similar to usual moments, but they can often be more stably estimated.

and wiki:

L-moments are a kind of moments based on linear functions of order statistics. Their interpretation is similar to usual moments, but they can often be more stably estimated.

Their use was pioneered in hydrology, as a help in studying the form of probability distributions. See https://en.wikipedia.org/wiki/L-moment.

  • $\begingroup$ (+1) Too bad the tags cannot have upper-case letters (or serif fonts). I just hope we never have to compute L-moments for moments of intertia $I$! $\endgroup$ – GeoMatt22 Sep 22 '16 at 3:49
