Kev piav qhia: Raws li txoj cai ntawm kev sib raug zoo coefficients, qhov kev sib raug zoo tshaj plaws yog txiav txim siab thaum qhov tus nqi ze tshaj rau +1 (kev sib raug zoo) lossis -1 (tsis zoo sib raug zoo). Qhov zoo sib txheeb coefficient qhia tias tus nqi ntawm ib qho kev sib txawv nyob ntawm lwm qhov sib txawv ncaj qha.
Yog 0.4 Ib qho kev sib raug zoo?
Rau cov ntaub ntawv zoo li no, peb feem ntau xav txog kev sib raug zoo saum 0.4 kom muaj zog heev; Kev sib raug zoo ntawm 0.2 thiab 0.4 yog nruab nrab, thiab cov qis dua 0.2 yog suav tias tsis muaj zog. Thaum peb tab tom kawm tej yam uas suav tau yooj yim dua, peb cia siab tias muaj kev sib raug zoo dua.
Kev sib raug zoo tshaj plaws hauv kev puas siab puas ntsws yog dab tsi?
Kev sib raug zoo ntawm -1 txog 1, nrog kev sib raug zoo tshaj plaws ze dua rau -1 lossis 1. Kev sib txheeb ntawm 0 qhia tias tsis muaj kev sib raug zoo ntawm ob qhov sib txawv.
Ib.66 kev sib raug zoo?
76 yog kev sib raug zoo tshaj. The coefficient correlation is defined by the equation: r=cov(X, Y) / SxSy.
Yog 0.35 Ib qho kev sib raug zoo?
Labeling systems muaj nyob rau kwv yees li categorizer qhov tseem ceeb qhov kev sib raug zoo coefficients (hauv tus nqi tiag) uas yog < 0.35 feem ntau suav hais tias yog sawv cev qis lossis tsis muaj kev sib raug zoo, 0.36 txog 0.67 kev sib txheeb me me lossis nruab nrab, thiab 0.68 rau 1.0 muaj zog lossis siab sib raug zoo nrog r coefficients > 0.90 siab heev …
