Van Westendorp acceptable price range
I enter each respondent's four price answers and get back the deterministic Van Westendorp points (PMC, PME, OPP, IPP) on the observed price grid, so I have a defensible acceptable-price band.
You receive: A pure function computing {pmc, pme, opp, ipp} from per-respondent price answers, graded on hidden input->output cases against a held-out reference.

Scope of the check
What's verified: STUD verifies the function reproduces the declared discrete Van Westendorp convention exactly on hidden response sets: cumulative shares evaluated on the sorted grid of all supplied prices, each point being the first grid price where the rising curve meets or exceeds the falling one (PMC: not-a-bargain vs too-cheap; PME: too-expensive vs not-yet-expensive; OPP: too-expensive vs too-cheap; IPP: expensive vs bargain). STUD does NOT verify that the survey sample is representative, that respondents are real buyers, or that the band is the price to charge; and rows are expected price-ascending per respondent (too cheap <= bargain <= expensive <= too expensive).
