Excess yintoni. intsingiselo

Eli nqaku lichaza indima manani njengendlela inzululwazi. Ingqiqo kurtosis nokusetyenziswa kwayo kwisayensi.

Statistics. Le ngcamango

Amanani - yemvelaphi nenzululwazi ezisisiseko zemathematika. Le nto ibhekisa eziliqela ezentlalo, ezo ezijoliswe ekuphuhliseni abafundi 'imizobo Outlook kunye nohlalutyo abanobuchule lweziganeko.

Iinkcukacha-manani izifundo iinkqubo kunye neziganeko ezahlukeneyo kubomi babantu, oko kwenza ukuba ume ngaphandle iipatheni zonke ngohlobo iingxelo ezimfutshane manani. Le inzululwazi kuluncedo ngokwentlalo kwaye ifuna ukuphuculwa okuthe gqolo. Uchatha - ntoni na? Le ngcamango e manani lomzobo, nto leyo inceda ukufumanisa ukuchaneka calculus phambili. I-excess kufuneka angabi ukutenxa kwindlela olomeleleyo.

Statistics ikuvumela ukuba ukuhlangabezana nemfuno babantu iinkcukacha ezithembekileyo malunga ngezenzeko ethile, iziganeko njalo njalo. Nokuzimisela Dynamics imiba yobomi yokudodobala, ekuma okanye ukukhula - yiloo nto kanye le isayensi wenza.

Kweli hlabathi lanamhlanje-manani yenye indawo ephambili kwibala yenzululwazi. Makhe sijonge ingcamango "okugqithe". Yintoni injongo lwezibalo iliso? Apho la magama asetyenziswa? Konke oku, bona kamva kweli nqaku.

Yintoni agqithisile kwi-manani?

Excess - ingqiqo manani, nto leyo emele i-ndikho iphezulu ngamnye lonikezelo kwitshathi. Kukho indlela ekhethekileyo izibalo zalo ngqo.

Kulindeleke ithi ukuba iyunifomu ngakumbi manani nokwabiwa kurtosis kufuneka kulingana linani elidibanisayo. Ngokoqobo lo gama lithetha unxaxho ethile kwisiqhelo kunye nophuhliso ngakumbi engaqhelekanga okanye nokusebenza kwenkqubo zamanani.

yokubonakalisa kakhulu obugqithisileyo kwigrafu manani ukuthetha malunga ihambo ephosakeleyo zesifundo okanye impazamo kule grafu data ekrwada. Loo nto ke scalar kwindalo, nto leyo ethetha ukuba inguqulelo yokugqibela kufuneka bafumane inani elo ayiqulathanga imisebenzi eziguquguqukayo okanye abangabancedani. Nantso into kurtosis.

Yintoni lonikezelo twatsa kanye yezi zinto

Asele, nto leyo enkundla anxulumene nazo akusiwa lohlobo twatsa ngu zero. Kuyenzeka ukubonisa usebenzisa schedule. igrafu yezi ibonisa kakhulu inani zero. Libhekisela ukuya kwakuwo.

Yintoni na ndikho le incopho? Ishedyuli, nto leyo eye iincopho elibukhali, ibonisa ukuba ixabiso obugqithisileyo - eli nani lingaphantsi kwe-zero. Lidla kukho iimeko apho le ngcamango ukuthetha ixabiso enye. Kulo mzekelo, oko likufutshane thabatha okanye plus obungapheliyo.
