NAME

deep-finance-survival-sale-time — "Median time-to-sale for your cuff at $48 is 71 days; 25/75 percentile band $34–$112. Worth renewing."

SYNOPSIS

id deep-finance-survival-sale-time tier deep-purple section §22. Finance — AI/subsystem + deep-purple cluster (37) trigger analysis-pattern shape SINGLE

DESCRIPTION

Borrowed from medical research: estimate how long until a listing 'dies' (sells), with a confidence band. Censored data (still on the shelf) contributes too — we don't pretend it sold at the cutoff.

"Median time-to-sale for your cuff at $48 is 71 days; 25/75 percentile band $34–$112. Worth renewing."

EXAMPLES

Sakura uses this when you ask "how long should I wait before relisting?" Survival analysis treats time-to-sale like a clinical trial — accounting for the listings still alive without a sale. "Median 71 days at $48. Worth renewing."

FITNESS

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.
