Vim li cas ho tsis 100 feem pua ​​​​ siv tau rau FPC 100 feem pua ​​xeem

Nws yog ib qho kev xyaum ua 100 feem pua ​​​​kev tshuaj xyuas kom tsis txhob muaj cov khoom tsis raug xa mus. Txhua yam khoom tsim tau raug tshuaj xyuas thiab txiav txim kom dhau los yog ua tsis tiav. Cov khoom yuav raug xa tawm thiab cov khoom tsis sib haum yuav raug tso tseg rau kev kho lossis cov khoom seem. Nws yog txhua yam yooj yim thiab ncaj nraim. Nws zoo nkaus li tias 100 feem pua ​​​​kev tshuaj xyuas yog ib txoj hauv kev zoo heev, tsis hais txog qhov ua yuam kev ntawm cov neeg soj ntsuam.

Peb xav hais tias tus yam ntxwv qhov tseem ceeb ntawm cov khoom yog ib txwm faib, qhia los ntawm Y, raws li qhia hauv daim duab hauv qab no.

Cov qauv tsim nyog ntawm cov khoom raug paub, thiab cov ntsiab lus tshwj xeeb ntawm cov kev txwv sab saud thiab qis kuj tau muab, xws li LSL thiab USL hauv daim duab saum toj no. Cov khoom nruab nrab ntawm LSL thiab USL yuav yog cov khoom tsim nyog. Tab sis peb tsis paub tus nqi Y tiag tiag, peb yuav tsum siv lub ntsuas ntsuas ntsuas, qhov ntsuas tus nqi Y yog hu ua X.

Qhov ntsuas X tus nqi tsis sib npaug rau Y, vim tias muaj qhov ntsuas qhov yuam kev, uas peb hu ua E. Vim tias qhov ntsuas qhov yuam kev kuj tseem raug faib, peb tau txais kev faib tawm ntawm qhov ntsuas tus nqi raws li qhia hauv daim duab hauv qab no, uas zoo ib yam li Qhov kev faib tawm ntawm Y, tab sis qhov sib txawv ntawm X yog qhov loj dua, sib npaug ntawm qhov sib txawv ntawm Y ntxiv rau qhov sib txawv ntawm qhov ntsuas qhov yuam kev E.

Tom ntej no peb siv bivariate ib txwm faib los qhia txog kev sib raug zoo ntawm Y thiab X.

Tus qauv probabilistic ntawm qhov kev faib tawm no tuaj yeem sawv cev los ntawm cov ellipses hauv XY lub dav hlau sib koom ua ke. Daim duab hauv qab no qhia tau hais tias ib, ob, thiab peb tus qauv sib txawv ntawm ob qhov kev faib tawm ib txwm muaj, qhov twg cov intraclass correlation coefficients tau teeb tsa raws li {{0}}.95 thiab 0.80.

Raws li tuaj yeem pom los ntawm daim duab saum toj no, raws li kev ntsuas qhov yuam kev nce, lub ellipse ntawm bivariate ib txwm faib ua fatter thiab lub ntsiab axis yog skewed. Qhov peb xav tau yog: qhov ntau ntawm kev ntsuas X sib raug rau tus tsim nyog Y.

Cov kab dawb hauv daim duab hauv qab no qhia txog ntau yam ntawm cov khoom tsim nyog

Lub cim hauv qab no qhia txog ntau yam khoom xa tuaj tom qab 100 feem pua ​​​​kev tshuaj xyuas.

Nyob rau ntawm lub sijhawm no, peb tau pom meej tias qhov ntau ntawm cov khoom xa tuaj tom qab 100 feem pua ​​​​kev tshuaj xyuas yog txawv ntawm qhov ntau ntawm cov khoom tsim nyog.

Qhov ntau ntawm cov khoom uas dhau 100 feem pua ​​​​kev tshuaj xyuas ≠ qhov ntau ntawm cov khoom tsim nyog

Peb faib tag nrho cov khoom rau hauv plaub pawg raws li qhov zoo ntawm cov khoom thiab seb lawv puas raug xa los yog tsis:

Kev soj ntsuam cov khoom tsim nyog (GS: Zoo thiab Shipped)

Kev tshuaj ntsuam xyuas cov khoom tsis lees paub (GR: Zoo thiab tsis lees paub)

Cov khoom tsis tsim nyog dhau qhov kev tshuaj xyuas (BS: Phem thiab Shipped)

Kev tshuaj xyuas tsis tsim nyog tsis lees paub cov khoom (BR: Tsis zoo thiab tsis lees paub)

GS vs BR yog qhov tshwm sim peb xav pom, BS yuav ua teeb meem rau cov neeg siv khoom thiab GR yuav ua teeb meem rau nws tus kheej.

Cov duab hauv qab no qhia tau hais tias txoj haujlwm ntawm txhua pawg hauv bivariate ib txwm faib.

Rau cov neeg tsim khoom, nws cia siab tias qhov kev faib ua feem ntawm cov khoom tsim nyog xa khoom (PGS: Qhov feem ntawm cov khoom zoo uas raug xa tawm) yog siab npaum li qhov ua tau:

PGS=GS / (GS plus GR1 plus GR2)

Rau cov neeg siv khoom, qhov nws xav tau yog qhov feem pua ​​​​ntawm cov khoom tsis zoo uas tsis lees paub (PBR: Qhov feem pua ​​​​ntawm cov khoom tsis zoo uas tsis lees paub) yog siab npaum li qhov ua tau:

PBR=(BR1 ntxiv rau BR2) / (BR1 ntxiv rau BR2 ntxiv rau BS1 ntxiv rau BS2)

Hmoov tsis zoo, PGS thiab PBR tsis muaj feem cuam tshuam.

Hauv qab no yog lub rooj ntsuam xyuas qhia txog qhov tseem ceeb ntawm PGS thiab PBR rau ntau theem ntawm kev ntsuas qhov yuam kev thiab qhov feem ntawm tag nrho cov khoom tsis sib haum.

Txhais cov ntaub ntawv nyob rau hauv qab txoj cai kaum ntawm cov lus saum toj no: thaum tag nrho cov khoom tsis ua hauj lwm tus nqi yog 1 feem pua ​​thiab qhov kev ntsuas qhov yuam kev yog loj (ICC=0.8), cov neeg tsim khoom yuav muaj 98.6 feem pua ​​​​qhov tshwm sim ntawm shipping cov khoom tsim nyog, tab sis qhov kev faib ua feem ntawm cov khoom tsis raug lees paub tsuas yog 70 feem pua, thiab cov khoom lag luam loj yuav ntws mus rau cov neeg siv khoom.

Yuav daws qhov teeb meem no li cas? Zoo li tsuas muaj ob txoj kev xwb.

Thawj txoj kev: ua raws li 100 feem pua ​​​​ntawm kev xeem, tom qab ntawd txhim kho qhov kev ntsuas, kom cov ellipse nyob rau hauv bivariate ib txwm faib yog flattened zoo li ib txoj kab ncaj nraim, ces ob qho tib si PGS thiab PBR yuav siab heev.

Tus nqi yog: koj xav tau lub kaw lus ze-zoo meej ntsuas, uas feem ntau xav tau kev nqis peev loj uas tsis daws qhov teeb meem, nws tsuas yog tso nws tom qab.

Qhov thib ob txoj kev: Txhim kho cov txheej txheem muaj peev xwm kom cov zis ntawm cov txheej txheem nyob rau hauv cov kev txwv sab sauv thiab qis ntawm qhov kev qhia tshwj xeeb. Lub sijhawm no, 100 feem pua ​​​​kev tshuaj xyuas tsis tas yuav tsum tau ua lawm, uas tuaj yeem tsis tsuas yog txuag kev nqis peev hauv kev txhim kho qhov kev xeem, tab sis kuj txuag tus nqi ntawm kev tshuaj xyuas, thiab ntau dua. Lub ntsiab lus yog los daws qhov teeb meem tiag tiag.

Txog tam sim no, peb cov lus xaus yog qhov tseeb heev:

Qhov tshwm sim ntawm kev ntsuas qhov yuam kev ua rau 100 feem pua ​​​​kev tshuaj xyuas tsis tuaj yeem muaj 100 feem pua ​​​​ siv tau;

100 feem pua ​​​​kev tshuaj xyuas tsis tuaj yeem daws cov teeb meem zoo, thiab nws tseem yuav xav tau cov cuab yeej siv tsis tsim nyog thiab cov nqi tshuaj xyuas cov neeg ua haujlwm;

Kev ntsuas qhov system yuav tsum tau siv los txhim kho qhov zoo thiab sib xws ntawm cov txheej txheem tsim khoom, tsis yog rau kev tshuaj xyuas.
