Talk:Rank-dependent expected utility

Original research issue

I proposed RDEU (then called Anticipated Utility) in 1982, and I'm also the only contributor to this article so far. However, I don't hink I'm violating WP:No original research as (i) The model was published in a refereed journal (ii) It's been used extensively since, notably in the Cumulative prospect theory of Daniel Kahneman and Amos Tversky.

Variable Definition

Any chance of defining the variables in the equations in the last section? Pkearney (talk) 18:29, 16 June 2009 (UTC)

Definition for h[1]?

I have a feeling the definition needs to be updated to specify the s=1 case in $h_{[s]}(\mathbf {\pi } )=q\left(\sum \limits _{t=1}^{s}\pi _{[t]}\right)-q\left(\sum \limits _{t=1}^{s-1}\pi _{[t]}\right)$? If s=1, second part is a sum of elements from 1 to 0? What is the convention in that case? — Preceding unsigned comment added by EtudiantEco (talk • contribs) 18:48, 5 November 2020 (UTC)

I added $h_{[S]}(\mathbf {\pi } )=q\left(\pi _{[S]}\right)$, following Diecidue, Enrico and Wakker, Peter P., On the Intuition of Rank-Dependent Utility.
