Coefficient ya asymmetry, coefficient ya asymmetry ndi kurtosis, momwe mungawerengere coefficient ya asymmetry, zosankha zowerengera za coefficient

Kokwanira kwa asymmetry si nkhani yophweka. Komabe, izi ndi maganizo a atsopano. Mukayang'anitsitsa, mawuwa akuphweka mosavuta. Izi mwina ndizofunikira kwambiri mu lingaliro lonse la mwayi. Ndi coefficient of asymmetry ndi kurtosis zomwe zimapangitsa kuwerengera ndi kuzindikira kwa mitundu yosiyanasiyana. Miyezo imeneyi imayesedwa ndi mayendedwe. Kuti mudziwe chomwe coefficient of asymmetry, muyenera kudziwa mfundo zotsatirazi: kukula kwa torque pakati ndi mtengo wa kupotoka. Komanso, m'pofunika kuti X, yomwe imatanthauza coefficient palokha, imadziwika kukhala yoperewera. Apo ayi, ziwerengero zonse ndi zopanda phindu. Ndi X sitikutanthauza nambala yokwanira. Kuti mupeze yankho loyenera ndikupeza chomwe coefficient of asymmetry chiri mu vuto lina, muyenera kugwiritsa ntchito maumboni angapo. Ndikofunika kuti zotsatira zomwe mumapeza zimakhala pafupi ndi zero.

Nchifukwa chiyani kuli kofunikira kuwerengera chiwerengero cha asymmetry? Izi ndizofunika kusonkhanitsa deta ndikuwonetsa zotsatira. M'madera onse a ntchito, ziwerengero zimakhala ndi ntchito yofunikira. Choyezera cha asymmetry pazochitika zake zimathandizira kuwerengera khalidwe la zomangamanga pambuyo pomanga, kuthekera kwa kuwonongeka kwake, motero kumathandiza kutenga njira zotetezera zochitika zoterezi. Ndipo izi sizikutanthauza kuti ntchitoyi yapamwambayi imakhala yopanda nzeru. Izi ndi momwe kugwiritsira ntchito chitoliro ku flange kumawerengedwa asanatengeke, zogwirizana ndi zomangamanga zilizonse zikulingalira ... Zivomerezani, ndi kosavuta kuwerengera coefficient ya asymmetry ndi kuteteza cholakwika chotheka kuposa kumanga nyumba kapena kuyika gawo, ndipo Kenako bweretsani. Sizowonjezereka zokha, koma komanso zotsika mtengo: chifukwa kutembenuka, monga lamulo, ndalama zambiri zimagwiritsidwa ntchito.

Mu machitidwe ochiritsira, chiwerengero cha asymmetry chimatchulidwa monga As. Monga lamulo, zopotoka zoterezi zanenedweratu ndipo zinayambitsidwa, zomwe sizinali zoona. Izi zimachitidwa kuti muwone mmene dongosolo lonseli limakhalira, ngati cholakwikacho, ngakhale chochepa, chimachitika. Zimakhulupirira kuti zolakwika zilizonse zimakhalapo. Chokhacho chingathe kuwononga chilichonse, kapena kukhalabe chopanda phindu komanso kusasintha. Cholakwika ichi chikhoza kunenedweratu ndipo chiwerengero cha coefficients of asymmetry ndi kurtosis chimathandiza.

Palinso njira zambiri zowerengera zomwe zimadziwika kuti ndi zothandiza, koma chokhacho chokha chimaphatikizapo kuyang'ana posachedwa komanso mwinamwake, njira zina zomwe sizingapereke. Zina mwazo: ziŵerengero za malamulo, ziwerengero zowerengera, ndi zina zotero.

Mwa njira, kuti muwerenge coefficient iyi, mutha kusonkhanitsa kapena chidziwitso chomwe chaphatikizidwa, kapena ngakhale chobala, chiwerengero chosadziwika.

Ziwerengero izi zimagwiritsidwa ntchito nthawi zambiri mu sayansi ya chilengedwe, komanso mabanki, nthawi zonse muzowerengera zomangamanga, chifukwa zizindikiro zawo ndi zolondola kwambiri komanso zowona. Kugwiritsa ntchito ziwerengerozi kumateteza zolakwika zomwe zingakhale zosayembekezereka.

Choncho tengani vuto kupeza zowonjezera zabwino kwa kampani yanu, kuti musayambe "kutentha" mulimonsemo. Adzatha kufotokozera zomwe zikuchitika pazochitika zanu pazinthu zomwe simukuzidziwa, komanso m'njira zambiri bwino. Ndipotu, ziwerengero zimapindula kuposa mawu: nthawi zonse zimakhala zolondola. Mwa njira, mukhoza kudziwerengera nokha, ngati simukudziwa bwino masamu. Zangokwanira kuti mutsegule buku labwino pazomwe mukuwerengera ndikuganizirani ndime zomwe zimanena za coyfficient ya asymmetry. Mwamwayi!
