Beta ( β ) hais txog qhov tshwm sim ntawm hom II yuam kev hauv a txheeb cais kev sim siab Feem ntau, lub zog ntawm kev xeem, sib npaug li 1– β dua li β nws tus kheej, raug xa mus rau qhov ntsuas ntawm qhov zoo rau qhov kev ntsuas qhov kev xav.
Hauv qhov no, beta txhais li cas hauv StATS?
Cov beta theem (feem ntau hu ua yooj yim beta ) yog qhov tshwm sim ntawm kev ua hom II yuam kev (lees txais qhov kev xav tsis meej thaum qhov kev xav tsis raug yog qhov tsis raug). Nws yog ncaj qha ntsig txog lub hwj chim, qhov tshwm sim ntawm kev tsis lees paub qhov kev xav tsis zoo thaum lub null hypothesis tsis tseeb.
Ib tus kuj tseem yuav nug tau, dab tsi yog qhov regression? Cov beta coefficient yog qhov kev hloov pauv ntawm cov txiaj ntsig tau hloov pauv rau txhua 1-unit ntawm kev hloov pauv hauv qhov ntsuas qhov sib txawv. Yog hais tias tus beta coefficient tsis zoo, kev txhais lus yog tias rau txhua 1-chav nce hauv qhov kwv yees sib txawv, qhov txiaj ntsig sib txawv yuav txo los ntawm beta tus nqi coefficient
Kuj paub yog, dab tsi yog beta hauv psychology?
beta qib. qhov zoo li ntawm qhov tsis lees paub qhov kev xav tsis meej thaum nws yog qhov tseeb tsis tseeb, uas yog, qhov tshwm sim ntawm ua hom II yuam kev. Cov beta qib rau cov txheej txheem txheeb cais muaj feem cuam tshuam nrog lub zog ntawm cov txheej txheem ntawd (β qib = 1 - lub zog).
Dab tsi yog beta -yuam kev siv los ntsuas?
Ib Hom I yuam kev yog qhov tsis lees paub qhov tseeb qhov kev xav tsis raug. Ib hom II yuam kev yog qhov uas koj tsis kam lees qhov tsis tseeb null hypothesis. A beta qib, feem ntau tsuas yog hu ua beta ( β ), yog qhov rov qab; qhov tshwm sim ntawm kev lees txais qhov null hypothesis thaum nws tsis tseeb.
