The coefficient tsa asymmetry, skewness le kurtosis ka ho a bale asymmetry coefficient manolotsoeng coefficient embodiments

skewness - ya kgopolo ya ho e ho se bonolo. Leha ho le joalo, sena ka maikutlo a ba qalang. Holim 'a ba ngotse hlahlobo atamela, lentsoe lena ke ho le bonolo haholo ho silehe. Sena ke mohlomong e leng khopolo bohlokoa ka ho fetisisa kgonego tsohle. Hore skewness le kurtosis kgothaletsa dikhomphiutha le boitsebiso ba divariabole tšohanyetso. makgabane tsena di balwa ka mekhoa. E le hore a tsebe se ka coefficient tsa asymmetry, ho ke ho hlokahala hore ho tseba hore na ke boitsebiso bo latelang: nako boleng ba karolong e bohareng ea boleng le tekanyetso kheloha. Ho feta moo, ho ke ke ho hlokahala hore X, eo e denoted ka boeona coefficient ne sebele tlase ho egoist. Ho seng joalo, dipalelo tsohle ke lefeela. X ho ba ha e le palo e lekanyelitsoeng. E le hore ho fumana tharollo loketseng 'me u fumane hore na ke eng ke asymmetry coefficient ena kapa Tabeng eo, u tla lokela ho sebelisa tse' maloa ho feta mekhoa. Ho tse lakatsehang hore sephetho o fumana haufi le lefela.

Ke hobane'ng ha e le habohlokoa hore a bale asymmetry? Ho ke ke ho hlokahala bakeng sa pokello ea sephetho dipalopalo ya data le giorni. Likarolong tsohle tsa lipalo-palo phetha karolo ea bohlokoa. The asymmetry coefficient tabeng ea ho lokisetsa thusa ha ho baloa boitšoaro ba moaho mora oa kaho, le monyetla oa ho timetsoa ha eona, 'me kahoo o thusa ho nka mehato ea ho thibela maemo a tšoanang. Sena ha se e sebetsa nyeoe ea ka thōko, eo ka ho eona tshebetso thuto ea lipalo, sena e utloahalang: kahoo ba balwa mabapi le phala e nang le flange pele ho tjheseletsa, ho hlwaya leha e le efe e lekanyelitsoeng lichifi Construction ... Lumellanang pete ho a bale skewness le ho thibela phoso ho khoneha, ho feta ho haha mohaho kapa karolo welded, 'me ebe go mpshafatsa. Sena ha se e loketseng feela empa hape theko e tlaase: rework, ba atisa ho qeta nako e ngata ea chelete.

Ka mekhoa tloaelehileng asymmetry coefficient e denoted ka As. E le busa, ba bolela esale pele 'me a kenyelletsa joalo diphapano tšohanyetso hore ha e le hantle. Sena se etsoa ho hlahloba kamoo re ka itšoara ka tsamaiso eohle mehaho ka kakaretso ha sena se etsahala, esita le ho phoso bonyane. Ho lumeloa hore haeba leha e le phoso e bang teng. Feela a ka ka senya sohle kapa ba lule ba e nyenyane 'me u se ke ua senya sebopeho sa. Noha phoso 'me a thusa manolotsoeng tsa skewness le kurtosis.

Ho na le e ngata ea tšoanang mekhoa dipalopalo, eo hape a tsejoang ka utility bona, empa feela asymmetry Ntlha e khothalletsa latedisa tsa nakong e tlang haufi le kgonego ya ke keng fana litsela tse ling. Har'a bona: Order Lipalo-palo, boemo lipalo-palo, joalo-joalo

Ka tsela eo, e le hore a bale karo-karolelano ena, ho ka etsahala ho bokella tlhahisoleseding efe kapa efe e 'nileng ea hlophisitsoe kapa esita le tse ka thōko, e ke ke a phuthilweng hammoho lipalo.

dipalelo tsena tse hangata ka ho fetisisa sebelisoa ka saense ea tlhaho, hammoho le khoebo ho banka, kamehla ka metsana efe kapa efe ea lehae hobane ditefello tsa bona li nepahetse ka ho fetisisa 'me batho ba lumele. Sebelisa dipalelo tsena e tla sireletsa khahlanong le morago ga moo e, liphoso mohlomong le bolaeang.

Kahoo tsa nka khathatso ho se fumana e ntle statistician bakeng sa khampani, a se ke a "ba chesa ka boeona e ho tsoa" ka ho leha e le efe joalo. O tla kgona ho bolela esale pele boemo bona ka litaba tsa sehlopha hammoho le leha e le efe senohi, 'me ka litsela tse ngata - le ho feta. Mora linomoro tsohle na le molemo holim'a mantsoe a reng, ba kamehla nepahetse. Ka tsela eo, u ka sebetsana le mekhoa le uena, haeba u na le e nyenyane a tseba thuto ea lipalo e phahameng. Mpa feela bula sao tutorial e ntle ka lipalo-palo le ho ela hloko lirapa ho bolella ka asymmetry coefficient. Mahlohonolo!
