Methods o tatauranga pāngarau. tātari inenga

Whakamahia te tātari wā regression maha timata Pearson (Pearson) i roto i ana mahi, teiti i te tau 1908 ano. whakaahuatia e ia te reira hei tauira o te kaihoko whakahaere te hoko o hoko whare. I roto i ona tuhipoka i runga i nga whare arahina Trade Specialist pūkete o te whānui o ngā raraunga pūtake o ia hanganga takitahi ngā. Na roto i te hua o ringarehe whakatau reira e take i te pānga nui i runga i te utu o te hoko.

ka hoatu e Tātaritanga o te maha nui o ngā whakawhitinga hua ngā. Ko te utu whakamutunga tākiekina e āhuatanga maha, i ētahi wā ārahi ki whakatau ihoa, me te ara mārama "tukunga", ka te whare ki te pūmanawa tuatahi tiketike hokona i te taupū utu iti.

homai he tauira tuarua o te tono o tenei tātaritanga te mahi kaimahi mātanga, i nei kua tukua whakatau hua kaimahi. takoto te wero i roto i te meka e kore ko te tohatoha hiahiatia he nui whakaritea mo ia, me te pipiki tino ki ona uara o te mahi motuhake whakamana. Ko te putanga o te momo o ngā mahi e te hunga rongoā kē tata rite, e rapu he arotake atu taipitopito i te taumata pāngarau.

I roto i te tatauranga pāngarau, i homai he wahi nui ki te wāhanga "tātaritanga inenga", i reira piri tikanga mahi whakamahia ki ako i te ririki hipoki e te ariā o te inenga o. E kitea ana ēnei whanaungatanga i waenganui i te raraunga whiwhi i roto i te tätari tauanga.

mahi tātari inenga i roto i te plurality o matua e toru ngā take: ki te tautuhi i te whārite inenga o o te puka whānui; hanga o tata tawhā e te hunga unknown, e kua whakaurua i roto i te whārite inenga o; taki inenga whakapae tauanga. I roto i te akoranga o ako te hononga e puta i waenganui i te rua o ngā uara hua i ngā kitenga whakamātautau, me te maha o ngā wāhanga (he tokomaha) patopato (x1, Y1), ..., (xn, yn), e hāngai ana i runga i te tūranga o te ariā inenga o me whakaaro e mo te uara kotahi Y i reira ko tetahi tohatoha tūponotanga, ahakoa te meka e tonu tetahi X whakaritea.

Ko te hua Y tei runga i te uara o te X tāupe, e taea te whakaritea i tenei fakafalala i ngā ture, te awe i te tika o nga hua e te āhua me te whakaaro o te tātaritanga o ngā kitenga. E hāngai ana te tauira whakamātau te i runga i etahi whakapae e he māmā engari reka. Ko te huru matua ko e te mana te uara o te tawhā X te. E hoatu Ko tōna uara i mua ki te tīmatanga o te whakamātau.

Ki te i roto i te akoranga o te whakamātau, he rua o taurangi haere noa nga XY, kawea te tātari inenga o roto i te tikanga kotahi, engari mo te tikanga o nga hua, i roto i nei ako tatou te ako hononga o ngā taurangi matapōkere, whakamahia tikanga o tātari te faatanoraa. e kore e he kaupapa waitara tikanga tauanga. kitea ratou tono i roto i te ora i roto i mara ngā o te mahi a te tangata.

I roto i te tuhinga pūtaiao ki te whakatau i te tikanga whakahuatia i runga ake, kua kitea whānui o te wā whakamahi rārangi inenga tātari. Hoki te tāupe whakamahia X te regressor wā kaimatapae ranei me taurangi ririki huaina Y-hoki criterial. whakaata ana tēnei kupu i te taurangi hononga pāngarau, engari e kore e tirotiro hononga causal.

tātaritanga inenga Ko te tikanga nui rawa mō whakamahia e te i te tukatuka o nga hua o te whānui o ngā kitenga momo. mahi tinana, me te koiora ako i te tikanga o tenei tikanga, kua whakatinanahia reira me te ōhanga, me i te toi. atu wāhi Mass whakamahi inenga o tauira tātari. Tātaritanga o whawhai, hoahoa o ngā, te tātaritanga tauanga o te mahi multidimensional tata ki tenei ara o te ako.
