Yogawa Normal kapena kugawa ya Gauss

Mwa malamulo onse a chiphunzitso Mwina, kugawa wabwinobwino amapezeka nthawi zambiri, kuphatikizapo zambiri kuposa yunifolomu. Mwina zodabwitsazi kwakuya lofunika chikhalidwe. Ndipotu, mtundu uwu yogawa zimawonedwa pamene mu chifaniziro cha uthunthu wa zosintha mwachisawawa nawo zinthu zingapo, zomwe zimakhudza njira zawo. The yachibadwa (kapena ya Gauss) yogawa Pankhaniyi analandira chifukwa Kuwonjezera distributions zosiyanasiyana. Ndi kuyamika kufalitsa kwa omangidwa kwambiri yogawa wabwinobwino, ndi nalo dzina lake.

Pamene ife kulankhula za mtengo woipa, kaya ndi mvula mwezi, pa munthu ndalama ndi ntchito maphunziro m'kalasi, mu mawerengedwe a mtengo wake, monga ulamuliro, ntchito lamulo yachibadwa kugawa. Izi mtengo pafupifupi amatchedwa chiyembekezo ndi Zithunzi limafanana ndi munthu pazipita (zambiri amatchedwa M). Ndi kugawa moyenera pamapindikira ndi symmetrical ndi kulemekeza pazipita, koma mfundo imeneyi si nthawi zonse, ndipo chovomerezeka.

Pofotokoza malamulo wabwinobwino wa mwachisawawa variable yogawa nawonso ayenera kudziwa muyezo kupatuka (amaimira σ - Sigma). Iwo amasonyeza mawonekedwe a pamapindikira pa Zithunzi lapansi. The σ zikuluzikulu za pamapindikira adzakhala pofuna. Komano, ndi σ ang'onoang'ono, molondola kwambiri anatsimikiza pafupifupi phindu mu chitsanzo. Choncho, chifukwa rms lalikulu zolakwika kunena kuti phindu avareji mkati osiyanasiyana ena a manambala, ndipo alibe zizigwirizana ndi kuchuluka iliyonse.

Komanso malamulo ena a ziwerengero lamulo yachibadwa lafalitsidwa Mwina khalidwe labwino kuposa zikuluzikulu chitsanzo, ie, chiwerengero cha zinthu zimene zimakhudzidwa miyezo ya. Komabe, apa imasonyezedwa zotsatira wina: chitsanzo chachikulu amakhala ochepa Mwina kupeza phindu kotsimikizika, kuphatikizapo pafupifupi. mfundo Only yagawidwa pafupi ndi pakati. Choncho zolondola kunena kuti variable mwachisawawa kukhala pafupi ndi mtengo yotsimikizika ndi Mwina ena.

Kudziwa momwe mwina ndi kuthandiza kupatuka muyezo. Mu "atatu Sigma" imeneyi, ie, M +/- 3 * σ, aikidwa 97,3% ya zedi zonse chitsanzo, ndi "zisanu Sigma" osiyanasiyana - za 99%. intervals izi chotchuka ntchito kudziwa pamene kuli kofunikira, pazipita ndi osachepera phindu mu chitsanzo. N'kutheka kuti phindu la imeneyi kuchokera Sigma zisanu, ndi negligible. Zochita Nthawi zambiri ntchito atatu Sigma imeneyi.

yogawa zimaikidwa multidimensional. Amaganiza kuti chinthu ali magawo angapo palokha, m'kukoma unit chomwecho muyeso. Mwachitsanzo, zopatuka wa chipolopolo ku likulu chandamale vertically ndi horizontally pa mfuti adzakhala anafotokoza ziwiri ooneka enieni yogawa yachibadwa. The Zithunzi lafalitsidwa mu nkhani yabwino ngati chithunzi kusintha ndege pamapindikira (ya Gauss), monga taonera pamwambapa.
