Tshem tawm qhov sib txawv, yog li, kev tsis ncaj ncees rau lwm qhov sib txawv.
Nws txhais li cas yog qhov hloov pauv tsis tseem ceeb?
The tsis muaj qhov tseem ceeb txhais tau tias tsis muaj teeb liab ntau npaum li qhov tau sau tsis muaj ntaub ntawv txhua. Tus nqi nkaus xwb nyob rau hauv cov ntaub ntawv ntawm lub sijhawm no yog sib txuas nrog cov ntaub ntawv tshiab kom koj tus qauv loj loj. Tab sis txawm tias tom qab ntawd koj yuav ua tiav qhov tseem ceeb tsuas yog tias cov txheej txheem koj tab tom kawm ua tau tiag tiag. Cite.
Yuav ua li cas yog qhov tshwm sim ntawm qhov tsis sib xws?
Thaum muaj qhov sib txawv tsis tseem ceeb suav nrog, qhov kev thim rov qab tsis cuam tshuam rau kev tsis ncaj ncees ntawm OLS tus kwv yees tab sis nce lawv qhov sib txawv.
Dab tsi yog qhov hloov pauv tsis tseem ceeb hauv kev thim rov qab?
Conversely, qhov loj dua (tsis tseem ceeb) p-tus nqi qhia tias kev hloov pauv ntawm tus kwv yees tsis cuam tshuam nrog kev hloov pauv hauv cov lus teb. … Feem ntau, koj siv cov coefficient p-values los txiav txim seb cov nqe lus twg yuav khaws cia rau hauv tus qauv regression. Hauv cov qauv saum toj no, peb yuav tsum xav txog kev tshem tawm East.
Yuav ua li cas yog cov ntaub ntawv tsis tseem ceeb?
Thaum tus p-tus nqi txaus txaus (piv txwv li, 5% lossis tsawg dua), ces cov txiaj ntsig tsis yooj yim piav qhia los ntawm lub sijhawm ib leeg,thiab data yog suav tias tsis sib haum nrog cov kev xav tsis tseeb; Nyob rau hauv cov ntaub ntawv no, lub null hypothesis ntawm lub caij nyoog ib leeg raws li ib tug piav qhia ntawm lub datayog tsis lees paub los ntawm kev piav qhia ntau dua.
