Maskinlærings-augmenteret instrumentvariabel-analyse (ML-IV)

Maskinlærings-augmenteret instrumentvariabel-analyse kombinerer den kausale identifikationskraft af klassisk IV med moderne højdimensionel maskinlæring — ved brug af metoder som LASSO, random forests eller neurale netværk til at udvælge gyldige instrumenter og modellere nuisance-funktioner, hvilket forbedrer first-stage fit og muliggør gyldig inferens, selv når antallet af potentielle instrumenter eller kontrolvariable er stort i forhold til stikprøvestørrelsen.
