NAME

deep-finance-bayesian-ab-price — "After 18 views + 3 sales: 72% probability the $40 price is better. Run two more days for a decisive call."

SYNOPSIS

id deep-finance-bayesian-ab-price tier deep-purple section §22. Finance — AI/subsystem + deep-purple cluster (37) trigger event (variant test) shape PLAYBOOK

DESCRIPTION

Two prices, watch the buyers. After every sale we update our belief about which price wins. Stop when we're confident enough — no need for the rigid fixed-sample-size test, no need to pre-pick a winner.

EXAMPLES

Sakura uses this when you're testing two prices and don't want to wait forever. Bayesian A/B tells you the running probability that one is better — "72% likely the $40 price wins, give it two more days for a confident call" — instead of demanding a fixed sample size like classical stats.

FITNESS

Not yet

This method only gives a real answer above a sample threshold. Running it on a small shop produces a confidence band the size of the universe — useless. When the shop crosses the threshold, this lights up.
