TSAB NTAWV. PROC UNIVARIATE yog tus txheej txheem hauv BASE SAS ® feem ntau yog siv rau kev tshuaj xyuas kev faib cov ntaub ntawv, suav nrog kev ntsuam xyuas ntawm qhov qub thiab kev tshawb pom ntawm cov neeg tawm.
Khaws qhov no hauv kev xav, qhov txawv ntawm proc txhais tau tias thiab proc univariate yog dab tsi?
Saib lub ntsiab qhov sib txawv ntawm ob txoj kev. 1. PROC txhais tau tias tuaj yeem xam ntau cov ntsiab lus feem pua xws li 1st, 5th, 10th, 25th, 50th, 75th, 90th, 95th, 99th feem pua tab sis nws tsis tuaj yeem suav cov feem pua ntawm kev cai xws li 20th, 80th, 97.5th, 99.5th feem pua. Txawm li cas los xij, PROC UNIVARIATE tuaj yeem khiav kev cai feem pua.
Qhov thib ob, qhov txawv ntawm proc txhais tau li cas thiab cov ntsiab lus proc hauv SAS yog dab tsi? Cov qhov sib txawv ntawm ob txheej txheem yog li ntawd PROC txhais tau tias tsim ib daim ntawv qhia los ntawm lub neej ntawd, whereas PROC SUMMARY tsim cov ntaub ntawv tso tawm los ntawm lub neej ntawd. Yog li yog tias koj xav tau daim ntawv tshaj tawm luam tawm rau cov npe - siv proc txhais - yog tias koj xav tau cov ntaub ntawv dhau mus rau cov ntaub ntawv teev rau kev siv ntxiv - proc cov ntsiab lus tej zaum yuav yog qhov kev xaiv zoo dua.
Ib yam li ntawd, tib neeg nug, ua li cas proc univariate xam cov feem pua ?
Yog tus naj npawb ntawm PCTLNAME = qhov tseem ceeb yog tsawg dua tus naj npawb ntawm feem pua (s) lossis yog tias koj tso tseg PCTLNAME=, PROC UNIVARIATE siv feem pua raws li lub ntsiab lus los tsim lub npe ntawm qhov sib txawv uas muaj cov feem pua . Rau tus lej feem pua , PROC UNIVARIATE siv feem pua.
Proc transpose ua dab tsi hauv SAS?
PROC TRANSPOSE pab kom rov kho cov ntaub ntawv hauv SAS . Txhawm rau txuag lub sijhawm programming thiab tswj qhov tseeb ntawm cov lej, peb yuav tsum siv TRANSPOSE txheej txheem rau restructure cov ntaub ntawv. Hloov Cov ntaub ntawv nrog PROC TRANSPOSE . Piv txwv Data Set. Cia peb tsim cov ntaub ntawv piv txwv uas yog siv los piav txog qhov TRANSPOSE txheej txheem.
