Unstandardized coefficients yog 'raw' coefficients tsim los ntawm regression tsom xam thaum qhov kev soj ntsuam yog ua los ntawm thawj, unstandardized variablesTsis zoo li standardized coefficients, uas yog normalized unit-tsawg coefficients, ib tug unstandardized coefficient muaj units thiab 'lub neej tiag' nplai.
Kuv puas yuav tsum siv cov qauv beta coefficients uas tsis yog qauv?
Thaum koj xav nrhiav cov kev hloov pauv ywj pheej nrog ntau qhov cuam tshuam rau koj qhov sib txawv ntawm koj tus kheej koj yuav tsum siv cov qauv qauv los txheeb xyuas lawvTseeb, qhov sib txawv ywj pheej nrog tus qauv loj dua coefficient yuav muaj cuam tshuam ntau dua ntawm qhov sib txawv ntawm qhov sib txawv.
β yog dab tsi nyob rau hauv regression?
Cov beta coefficient yog qhov kev hloov pauv ntawm qhov txiaj ntsig hloov pauv rau txhua 1-unit ntawm kev hloov pauv hauv qhov ntsuas qhov sib txawv… Yog tias beta coefficient yog qhov zoo, kev txhais lus yog rau txhua txhua 1-unit nce nyob rau hauv tus kwv yees qhov sib txawv, qhov tshwm sim kuj sib txawv yuav nce los ntawm tus nqi beta coefficient.
Tus qhab nia nyoos uas tsis tau ntsuas tus qauv regression coefficient qhia rau koj li cas?
Unstandardized regression coefficients qhia rau koj yuav hloov npaum li cas hauv Y (tus nqi yog B) yog kwv yees / kwv yees yuav tshwm sim rau ib chav hloov pauv hauv qhov hloov pauv ywj pheej (X), thaum tag nrho lwm cov IVs yog nyob tas li. Cov no khaws cov kev ntsuas tus kheej ntawm IVs thiab DV.
Koj txhais li cas cov coefficients tsis raug cai?
Cov coefficients tsis muaj txiaj ntsig yog siv los txhais cov txiaj ntsig ntawm txhua qhov sib txawv ntawm qhov tshwm sim. Lawv txoj kev txhais lus yog ncaj nraim thiab intuitive: Tag nrho lwm cov kev hloov pauv tau nyob tas li, qhov nce ntawm 1 chav nyob hauv X iyog txuam nrog qhov hloov pauv nruab nrab ntawm β i units hauv Y.
