Bayesian Structural Time Series

Bayesian Structural Time Series (BSTS) er et state-space modelleringsframework, introduceret af Scott og Varian (2014), der nedbryder en tidsserie i additive komponenter — trend, sæsonudsving og regression — og estimerer dem samtidigt gennem Bayesiansk inferens. Det danner grundlag for Googles CausalImpact-bibliotek og er et kraftfuldt værktøj til både prognoser og kontrafaktisk kausal analyse af interventioner.
