Bartlett's test of Homogeneity of Variances yog test kom paub seb puas muaj qhov sib npaug sib npaug ntawm qhov sib npaug lossis ntu ntu ntawm qhov sib txawv ntawm ob lossis ntau pawg ntawm categorical, ywj siab hloov pauv. Nws ntsuas qhov kev xav tsis tseeb ntawm tsis muaj qhov sib txawv ntawm qhov sib txawv ntawm cov pab pawg.
Koj ua li cas yog qhov kev xeem Bartlett tseem ceeb?
Txais lossis tsis lees txais qhov kev xav tsis tseeb, raws li P-tus nqi thiab qib tseem ceeb. Yog tias tus nqi P-qhov loj dua qhov tseem ceeb, peb tsis tuaj yeem tsis lees paub qhov kev xav tsis zoo uas qhov sib txawv yog sib npaug ntawm pawg.
Puas yog Bartlett xeem Parametric?
StatsDirect muab parametric(Bartlet thiab Levene) thiab nonparametric (squared ranks) kev xeem rau kev sib npaug / homogeneity ntawm variance. Feem ntau siv cov kev ntsuas kev ntsuas ntsuas, xws li kev xeem t, piv txwv lossis lwm yam kev ntsuas ntawm qhov chaw.
Qhov txawv ntawm Bartlett qhov kev xeem thiab Levene qhov kev xeem yog dab tsi?
Levene qhov kev xeem yog lwm txoj hauv kev xeem Bartlett. Qhov kev xeem Levene tsis tshua muaj siab dua qhov kev xeem Bartlett kom tawm mus los ntawm qhov qub. Yog tias koj muaj pov thawj muaj zog tias koj cov ntaub ntawv ua qhov tseeb los ntawm qhov qub, lossis ze li qub, kev faib tawm, ces Bartlett qhov kev sim tau ua tau zoo dua.
Dab tsi yog qhov kev siv KMO tus nqi thiab Bartlett qhov kev ntsuam xyuas hauv qhov kev tshuaj ntsuam xyuas?
KMO thiab Bartlett xeem ntsuas tag nrho cov ntaub ntawv muaj ua ke. KMOtus nqi tshaj 0.5 thiab ib theem tseem ceeb rau Bartlett qhov kev xeem hauv qab 0.05 qhia tias muaj kev sib raug zoo hauv cov ntaub ntawv. Kev sib txawv sib txawv qhia tau hais tias muaj zog npaum li cas ib qho kev sib txawv ntawm kev sib raug zoo nrog lwm qhov sib txawv.
