Synthetic data

Resolutions

Resolutions are the cards the store shows a hesitating shopper, one per worry. Choose when each appears, preview it, check it against past shoppers, then apply it. Applied settings change the demo store the next time it loads.

When each card appears

A card shows only when Qualm is at least as sure as the threshold and has seen enough clues. Technically: the posterior for that doubt must reach the threshold, with a minimum number of doubt-bearing events.

Check these settings against past shoppers

Your current settings, replayed click by click over 1000 past visits. This shows who would have seen a card. It can't show who would then have bought; only a real experiment can. "Right worry" uses the simulated truth, so it's only measurable in this demo.
