Original research issue[edit]

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.

I agree completely. --Rieger 12:28, 9 August 2006 (UTC)[reply]

Variable Definition[edit]

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

Definition for h[1]?[edit]

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)[reply]

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.
