ARCH-LM test za klasterovanje volatilnosti

ARCH-LM test je Langranžov multiplikator-dijagnostički test Roberta Engla (1982) za autoregresivnu uslovnu heteroskedastičnost u rezidualima uklopljenog modela vremenskih serija. On proverava da li se varijansa greške menja tokom vremena i klasteruje u mirne i turbulentne periode, i predstavlja standardni preliminarni test pre uklapanja modela volatilnosti iz GARCH porodice.
