Yog cov ntaub ntawv graphs symmetrically, qhov kev faib tawm muaj xoom skewness, tsis hais ntev npaum li cas los yog rog cov tails. Peb qhov kev faib tawm qhov tshwm sim tau piav qhia hauv qab no yog qhov zoo-skewed (los yog txoj cai-skewed) kom nce qib. Kev faib tawm tsis zoo kuj tseem hu ua kev faib tawm sab laug.
txhais li cas yog skewness yog 0?
Tus nqi skewness tuaj yeem yog qhov zoo lossis qhov tsis zoo, lossis tseem tsis tau txhais. Yog tias skewness yog 0, cov ntaub ntawv zoo kawg nkaus symmetrical, txawm hais tias nws tsis zoo li cov ntaub ntawv tiag tiag hauv ntiaj teb. Raws li txoj cai dav dav ntawm tus ntiv tes xoo: Yog tias skewness tsawg dua -1 lossis ntau dua 1, qhov kev faib tawm yog skewed heev.
Thaum coefficient ntawm skewness yog xoom qhov kev faib yog?
Tus nqi ntawm xoom txhais tau tias tsis skewness txhua. Tus nqi tsis zoo loj txhais tau tias qhov kev faib tawm tsis zoo skewed. Tus nqi zoo loj txhais tau hais tias qhov kev faib tawm yog qhov zoo skewed.
Qhov twg yog qhov tseeb rau kev faib nrog xoom skewness?
Peb paub tias kev faib nrog xoom skewness yog symmetric … Qhov tseeb, qhov tsis yog --- symmetry implies xoom skewness (xav tias tus coefficient ntawm skewness muaj), tab sis xoom skewness tsis txhais hais tias symmetry.
Thaum kev faib khoom hais tias yuav skewed?
Ib qho kev faib tawm yog hais tias yuav skewed thaum cov ntaub ntawv cov ntsiab lus pawg ntau dua rau ib sab ntawm qhov ntsuas dualwm tus, tsim kom muaj qhov nkhaus uas tsis sib luag. Hauv lwm lo lus, sab xis thiab sab laug ntawm kev faib khoom yog qhov sib txawv ntawm ib leeg. Muaj ob hom skewed distributions.

Thaum tus lej sib npaug y yog tus lej sib npaug?
Thaum muab tus lej Y yog tus lej sib npaug X=xn – 1xn-2…. x0 siv me ntsis-pair recoding hauv Booth's algorithm, ib nrab cov khoom tsim tawm raws li cov lus hauv qab no. Nqe lus piav qhia: ALU tsis tuaj yeem faib cov lej ncaj qha, nws tsuas tuaj yeem ntxiv, rho tawm lossis ua haujlwm.
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.
Rau lub hauv paus ntawm kev faib tawm cov qauv uas yog ib qho kev sib koom ua ke?
Daim duab 1. Sutures yog cov pob qij txha pom nyob hauv pob txha taub hau xwb. Syndesmoses yog cov pob qij txha uas cov pob txha txuas los ntawm ib pawg ntawm cov ntaub so ntswg sib txuas, tso cai rau kev txav mus los ntau dua li hauv suture.
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.
In poisson faib txhais tau tias sib npaug rau qhov sib txawv?
Qhov nruab nrab thiab qhov sib txawv ntawm Poisson kev faib tawm yog tib yam, uas yog sib npaug rau qhov nruab nrab ntawm kev ua tiav uas tshwm sim hauv lub sijhawm muabntawm lub sijhawm. Vim li cas lub ntsiab lus thiab qhov sib txawv yog tib yam hauv Poisson kev faib tawm?
