Kev faib T yog ib qho piv txwv ntawm leptocurtic distribution. Nws muaj cov tails fatter dua li qub (koj tuaj yeem saib thawj daim duab saum toj no kom pom cov tails fatter). Yog li ntawd, qhov tseem ceeb ntawm tus menyuam qhov kev xeem t-test yuav loj dua qhov tseem ceeb ntawm qhov kev xeem z. Kev faib tawm.
Yuav faib dab tsi yog T tis?
Kev faib tawm T, tseem hu ua Tus Tub Kawm Ntawv t-kev faib tawm, yog hom kev muaj peev xwm faib tawm uas zoo ib yam li kev faib tawm ib txwm nrog nws lub tswb tab sis muaj tails hnyav dua. T kev faib tawm muaj lub caij nyoog ntau dua rau qhov muaj nuj nqis tshaj qhov kev faib tawm ib txwm, yog li cov tails fatter.
Kev faib tawm twg yog Leptokurtic?
Leptokurtic distributions yog faib nrog kurtosis zoo loj dua li qhov kev faib tawm ib txwm. Ib qho kev faib tawm ib txwm muaj kurtosis ntawm peb. Yog li ntawd, ib qho kev faib nrog kurtosis ntau dua peb yuav raug sau npe tias yog leptocurtic distribution.
Ib qho piv txwv ntawm kev faib tawm Leptocurtic yog dab tsi?
Ib qho piv txwv ntawm kev faib tawm leptokurtic yog Laplace faib, uas muaj cov tails uas asymptotically mus zero qeeb dua li Gaussian, thiab yog li tsim tawm ntau tshaj li qhov kev faib tawm ib txwm.
Kuv yuav paub li cas yog tias kuv cov ntaub ntawv yog Platykurtic lossis Leptokurtic?
K < 3 qhia a platykurtic distribution (flatter than aib txwm faib nrog luv tails). K > 3 qhia txog kev faib tawm leptokurtic (ntau tshaj qhov kev faib tawm ib txwm nrog cov tails ntev). K=3 qhia ib txwm "bellshaped" faib (mesokurtic). K < 3 qhia txog kev faib tawm platykurtic.
Pom zoo:
Puas yog kev faib tawm yog ib qho adjective?
The adjective divisive is related to verb divide, uas txhais tau tias "sib cais los yog rub lawv sib nrug." Cov khoom faib faib.

Puas yog f faib leptokurtic?
Qhov kev faib tawm no tuaj yeem yog leptokurtic lossis platykurtic. Puas F-distribution yog kev faib tawm tas mus li? Snedecor) lossis luv luv F-distribution yog txuas ntxiv qhov muaj peev xwm faib tawmnrog ntau [0, +∞), nyob ntawm ob qhov tsis qhia v1, v2 (Lovric 2011).
Nyob rau hauv qhov kev txiav txim siab yog qhov kev sib tw yog kev tawm tsam kev tawm tsam?
Lub Ntiaj Teb Beat paub txog nws tsis lees paub cov khoom siv thiab cov qauv niaj hnub, kev sim tshuaj, thiab kev ywj pheej ntawm sab ntsuj plig thiab kev sib deev. Nws hloov zuj zus nyob rau xyoo 1960 los ua ib feem ntawm hippie thiab loj dua counterculture txav.
Qhov twg yog qhov kev txiav txim siab rau kev tsis lees paub thiab rau kev ua kom muaj kev tawm tsam ntawm kev tawm tsam?
Kev qhuab ntuas tau siv los ntawm cov thawj coj loj hauv cov tub rog Romanrau txim rau cov koom haum lossis pab pawg loj ua txhaum cai, xws li kev ua phem, kev tawm tsam, kev tawm tsam, thiab kev tsis ncaj ncees, thiab rau lub pacification ntawm rebellious legions.

Lub faib khoom tsis siv rau kev faib tib yam txij li nws ua nrog kev sib tw, tab sis lub tswv yim ntawm kev faib lossis "sib cais" tuaj yeem siv los faib. Puas kev faib raug kaw raws li kev faib khoom? Raws li cov cuab yeej no, cov khoom ntawm cov lej lossis qhov sib txawv ntawm tus lej yog sib npaug rau cov lej lossis qhov sib txawv ntawm cov khoom.
