Cov ntaub ntawv tu . Ntxuav koj cov ntaub ntawv suav nrog kev saib xyuas cov teeb meem hauv cov cov ntaub ntawv uas koj tau xaiv los suav nrog rau kev txheeb xyuas. Muaj ob peb txoj hauv kev cov ntaub ntawv huv siv cov Record thiab Field Operation nodes hauv IBM® SPSS ® Modeler.
Kuj paub, kev tu cov ntaub ntawv txhais li cas?
Kev ntxuav cov ntaub ntawv los yog kev tu cov ntaub ntawv yog tus txheej txheem ntawm kev kuaj xyuas thiab kho (lossis tshem tawm) cov ntaub ntawv tsis raug lossis tsis raug ntawm cov ntaub ntawv teev tseg, rooj, lossis database thiab hais txog kev txheeb xyuas qhov tsis tiav, tsis raug, tsis raug lossis tsis muaj feem cuam tshuam ntawm cov ntaub ntawv thiab tom qab ntawd hloov, hloov kho, lossis tshem tawm cov qias neeg lossis ntxhib cov ntaub ntawv.
Tsis tas li ntawd, kev tshuaj xyuas cov ntaub ntawv SPSS yog dab tsi? Kev tshuaj xyuas cov ntaub ntawv (qee zaum hu ua " cov ntaub ntawv qw") yog tus txheej txheem los xyuas kom meej koj cov ntaub ntawv yog huv si thiab npaj mus ua ntej koj ua ntxiv statistical analyses. Cov ntaub ntawv yuav tsum tau kuaj xyuas kom paub tseeb tias qhov cov ntaub ntawv yog siv tau, txhim khu kev qha, thiab siv tau rau kev sim ua qhov kev tshawb xav.
Ib yam li ib tug yuav nug, dab tsi yog kev tu cov ntaub ntawv hauv kev tshawb fawb?
Kev tu cov ntaub ntawv suav nrog kev tshawb nrhiav thiab tshem tawm (lossis kho) ntawm qhov tsis raug thiab tsis sib xws hauv cov ntaub ntawv teeb lossis database vim yog kev noj nyiaj txiag lossis kev nkag tsis raug ntawm lub cov ntaub ntawv . Ua tsis tiav, tsis raug lossis tsis cuam tshuam cov ntaub ntawv raug txheeb xyuas thiab tom qab ntawd hloov, hloov kho lossis tshem tawm.
Koj ua li cas ntxuav cov ntaub ntawv tshawb fawb?
Kev Tshawb Fawb Cov Ntaub Ntawv Cleansing: Tsib kauj ruam los ntxuav koj cov ntaub ntawv
- Kauj Ruam 1: Ua ib daim qauv ntawm koj cov ntaub ntawv thiab siv cov ntawv ntawd rau kev ntxuav cov ntaub ntawv.
- Kauj ruam 2: Ua ob peb cov ntaub ntawv mini ntxuav kev sim khiav.
- Kauj Ruam 3: Txheeb xyuas "qhov tseem ceeb ntawm qhov sib txawv" hauv koj qhov kev tshawb fawb thiab txheeb xyuas qhov ua tiav "ua tiav".
