Thaum koj tab tom nrhiav los tsim tus qauv, qhov sib npaug, lossis kwv yees cov lus teb tseem ceeb, siv regression. Yog tias koj tab tom nrhiav kom nrawm nrawm cov kev taw qhia thiab lub zog ntawm kev sib raug zoo, kev sib raug zoo yog koj thawj koom ruam zoo tshaj.
Thaum twg kuv yuav tsum siv kev txheeb xyuas kev sib raug zoo?
Kev txheeb xyuas kev sib raug zoo yog ib txoj hauv kev ntawm kev ntsuas kev ntsuas siv los kawm txog lub zog ntawm kev sib raug zoo ntawm ob, ntsuas tus lej, qhov sib txawv tsis tu ncua (piv txwv li qhov siab thiab qhov hnyav). Qhov kev tshuaj xyuas tshwj xeeb no muaj txiaj ntsig thaum tus kws tshawb fawb xav tsim yog tias muaj kev sib txuas ntawm cov hloov pauv.
Vim li cas correlation phem rau regression?
Lub hom phiaj tseem ceeb ntawm kev txheeb xyuas qhov kev rov qab yog cais qhov kev sib raug zoo ntawm txhua qhov sib txawv ntawm tus kheej thiab qhov sib txawv. … Qhov kev sib raug zoo dua, qhov nyuaj dua nws yog hloov ib qho kev hloov pauv yam tsis hloov lwm qhov.
Dab tsi yog qhov sib txawv ntawm kev sib raug zoo thiab kev thim rov qab?
Kev sib txheeb yog ib qho kev ntsuas ntsuas uas txiav txim siab txog kev koom tes lossis kev sib raug zoo ntawm ob qhov sib txawv. … Correlation coefficient qhia txog qhov uas ob qhov sib txawv txav mus ua ke. Regression qhia txog qhov cuam tshuam ntawm hloov pauv ntawm chav nyob ntawm qhov kwv yees sib txawv (y) hauv qhov paub sib txawv (x).
Kev sib raug zoo thiab kev thim rov qab siv rau dab tsi?

Qhov twg yog qhov laj thawj tseem ceeb rau kev thim rov qab / tig rov qab lub tswv yim?
Lub hom phiaj yog txo cov nqi, ua kom cov haujlwm ua haujlwm zoo, lossis ua kom cov nyiaj ntsuab ntws ruaj khov. Peb lub hom phiaj tseem ceeb ntawm kev thim rov qab yog: Txoj Cai Hloov Kho - Qhov no yog lub tswv yim tsim kho dua tshiab. Nws hu kom rov kho cov haujlwm kom tau nyiaj ntau dua lossis tau txais txiaj ntsig.
Kuv puas yuav tsum muab cov lim dej tso rau hauv kuv lub qhov rov qab?
Tsis txhob tso cov lim dej rau hauv koj lub vents. Koj lub AC system yuav tsum muaj cov lim kom haum rau sab rov qab. Los ntawm kev tso cov khoom siv zoo, cov lim dej zoo ntawm lub qhov rov qab, koj yuav tshem tawm cov khoom ntawm huab cua ua ntej lawv tuaj yeem nkag mus rau AC system.
Dab tsi ntawm cov hauv qab no yuav tsum yog qhov kev xav ntawm txoj kev kos npe rov qab?
Yuav tsum tsis txhob muaj kev nkag tebchaws mus lossis kev tsiv teb tsaws chaw tawm ntawm cov pejxeem. Yuav tsum tsis muaj kev tuag ntawm lub cim thiab lub sijhawm rov qab los. Kev paub txog kev cim yuav tsum tsis txhob ua rau ib tus neeg ntau dua lossis tsawg dua yuav rov qab tau.
Kuv yuav tsum siv qhov kev hloov pauv lossis kev sib xyaw ua ke?
Li no, Permutation yog siv rau cov npe (kev txiav txim tseem ceeb) thiab Kev sib xyaw rau pawg (kev txiav txim tsis muaj teeb meem). Cov lus tso dag nto moo rau qhov sib txawv yog: "kev sib koom ua ke" yuav tsum tau hu ua "permutation lock"
Kuv yuav tsum xaiv qhov kev txawj ntse lossis kev sib npaug?
"Wisdom" yog hais txog cov khawv koob thiab khawv koob, "Vitality" rau kev noj qab haus huv thiab kev noj qab haus huv cov ntsiab lus, thiab "Sib npaug" rau qee qhov sib npaug ntawm ob. Yooj yim yooj yim, xaiv Kev Txawj Ntse yuav muab Sora ntau cov khawv koob tab sis kev noj qab haus huv tsawg dua.
