Qhov sib txawv tseem ceeb ntawm lub sijhawm series thiab cov ntaub ntawv hla ntu yog qhov sijhawm series cov ntaub ntawv tsom mus rau tib yam sib txawv dhau lub sijhawm thaum lub sijhawm hla Cov ntaub ntawv tsom mus rau ntau qhov sib txawv ntawm tib lub sijhawm. Tsis tas li ntawd, cov ntaub ntawv teev sijhawm muaj xws li kev soj ntsuam ntawm ib qho kev kawm ntawm ntau lub sijhawm sib txawv whereas, cov ntaub ntawv hla ntu muaj kev soj ntsuam ntau yam ntawm tib lub ntsiab lus. hauv lub sijhawm.
Teb xws li Kev Tshawb Fawb, Econometrics sau cov ntaub ntawv thiab tshuaj xyuas lawv. Cov ntaub ntawv yog ib qho tseem ceeb ntawm cov dej num xws li kev tshawb fawb, kev kwv yees thiab kev ua pov thawj theories. Muaj ntau hom ntaub ntawv. Ob ntawm lawv yog cov sijhawm series thiab cov ntaub ntawv hla ntu.
Lub Sijhawm Series Data yog dab tsi?
Lub Sijhawm series cov ntaub ntawv tsom mus rau kev soj ntsuam ntawm ib tus neeg ntawm lub sijhawm sib txawv feem ntau ntawm cov sijhawm sib xws. Nws yog cov ntaub ntawv ntawm tib lub sijhawm sib txawv ntawm lub sijhawm xws li lub hlis, quarters, xyoo thiab lwm yam. Lub sijhawm series cov ntaub ntawv siv daim ntawv Xt. Lub t sawv cev rau lub sijhawm. Hauv qab no yog ib qho piv txwv ntawm cov txiaj ntsig ntawm ib lub koom haum nyob rau lub sijhawm 5 xyoos. Cov txiaj ntsig yog qhov sib txawv uas hloov txhua xyoo.
Feem ntau, cov ntaub ntawv teev sijhawm muaj txiaj ntsig zoo hauv cov ntawv thov kev lag luam. Kev ntsuas lub sij hawm tuaj yeem yog lub hlis, quarters lossis xyoo tab sis nws tuaj yeem yog txhua lub sijhawm. Feem ntau, lub sijhawm muaj qhov sib txawv.
Cov ntaub ntawv hla ntu yog dab tsi?
Hauv cov ntaub ntawv hla ntu, muaj ntau qhov sib txawv ntawm tib lub sijhawm. Cov ntaub ntawv teev nrog qhov kub siab tshaj plaws, av noo, cua ceev ntawm ob peb lub nroog hauv ib hnub yog piv txwv ntawm cov ntaub ntawv hla ntu.
Ib qho piv txwv yog cov nyiaj tau los ntawm kev muag khoom, muag ntim, tus naj npawb ntawm cov neeg siv khoom thiab cov nuj nqis ntawm lub koom haum hauv lub hli dhau los. Cov ntaub ntawv hla ntu yuav siv daim ntawv Xi. Kev nthuav tawm cov ntaub ntawv los ntawm ob peb lub hlis yuav hloov cov ntaub ntawv hla ntu rau cov ntaub ntawv teev sijhawm.
Qhov txawv ntawm Lub Sijhawm Series thiab Cov Ntaub Ntawv Hla Tebchaws yog dab tsi?
Lub Sijhawm series cov ntaub ntawv suav nrog kev soj ntsuam ntawm ib qho kev kawm ntawm ntau lub sijhawm. Cov ntaub ntawv hla ntu muaj kev soj ntsuam ntawm ntau yam ntawm tib lub sijhawm. Lub sij hawm series cov ntaub ntawv tsom rau tib qhov sib txawv ntawm lub sijhawm. Ntawm qhov tod tes, cov ntaub ntawv hla ntu tsom rau ntau qhov sib txawv ntawm tib lub sijhawm. Qhov no yog qhov sib txawv tseem ceeb ntawm lub sijhawm series thiab cov ntaub ntawv hla ntu.
Txoj txiaj ntsig ntawm ib lub koom haum nyob rau lub sijhawm 5 xyoos yog qhov piv txwv rau cov ntaub ntawv teev sijhawm thaum qhov kub siab tshaj plaws ntawm ntau lub nroog hauv ib hnub yog piv txwv rau cov ntaub ntawv hla ntu.
Summary – Sijhawm Series vs Hla Ntu Cov Ntaub Ntawv
Qhov sib txawv ntawm lub sij hawm series thiab cov ntaub ntawv hla ntu yog cov ntaub ntawv cov sij hawm series tsom rau tib lub sijhawm sib txawv ntawm lub sijhawm thaum cov ntaub ntawv hla ntu tsom rau ntau qhov sib txawv ntawm tib lub sijhawm. Cov ntaub ntawv sib txawv siv cov kev ntsuas sib txawv. Yog li ntawd, nws yog ib qho tseem ceeb kom paub qhov tseeb ntawm cov ntaub ntawv.
