2.5 Opaniraa

Ko nga wahi katoa raraunga Big, engari te whakamahi i te reira, me ētahi atu momo o raraunga observational mō te rangahau pāpori he uaua. I roto i toku wheako i reira he tahi mea rite kahore he taonga tina noa mō te rangahau: ki te kahore koutou e hoatu i roto i te rota o te mahi kohikohi raraunga, ka e haere pea koe ki te whai ki te hoatu i roto i te rota o te mahi tātari koutou raraunga ranei i roto i te whakaaro e pā ana ki he aha kei roto i te pātai ngā ki te ui o te raraunga. I runga i nga whakaaro i roto i tenei pene, whakaaro ahau e reira e toru ara matua e ka hei puna raraunga nui tino faufaa mō te rangahau pāpori:

• empirically whakawa i waenganui i te whakataetae matapae ariā. Tauira o tenei ahua o te mahi ngā Farber (2015) (New York Taxi atekōkiri) ko King, Pan, and Roberts (2013) (Rāhui i Haina)
• ake inenga pāpori mō te kaupapa here i roto i nowcasting. He tauira o tenei ahua o te mahi ko Ginsberg et al. (2009) (Google Rewharewha Te raveraa i).
• tata pānga causal ki ngā tūturu me ōrite. Tauira o tenei ahua o te mahi. Mas and Moretti (2009) (hoa pānga i runga i hua) me Einav et al. (2015) (pānga o te utu tīmatanga i runga i auctions i eBay).

taea e rave rahi mau uiraa faufaa i roto i te rangahau pāpori kia faaite rite tetahi o enei e toru. Heoi, enei huarahi te tikanga rapu kairangahau ki te kawe mai i te rota ki te raraunga. He aha hanga Farber (2015) ngā Ko te hihiri ariā mō te inenga. mai ana tēnei hihiri ariā i waho te raraunga. Ko te kupu, mo te hunga e pai i tono etahi momo o ngā pātai rangahau, puna raraunga nui e taea kia tino hua.

I te pae hopea, nui atu i te ariā-peia rangahau hōhonu (kua e kua te arotahi ki runga i tenei pene), ka taea e tatou e pore i te hōtuhi ka hanga theorizing empirically-peia. E te, i roto i te haaputuputuraa tupato o meka wheako, tauira, me ngā panga, tatou e nehenehe e hanga ariā hou.

E kore he mea hou tenei kē, huarahi raraunga-tuatahi ki te ariā, ka i tino kaha whakapuakihia reira e Glaser and Strauss (1967) ki to ratou karanga hoki ariā tūāpapa. Tenei huarahi raraunga-tuatahi, Heoi, e kore e whakapae "te mutunga o te ariā," kua rite kua kī i te nui o te kaikawe a tawhio noa rangahau i roto i te ao mamati (Anderson 2008) . Engari, rite nga huringa taiao raraunga, ti'a ia tatou ia titau i te re-whärite i roto i te hononga i waenganui i te ariā me te raraunga. I roto i te ao i reira te utu kohinga raraunga, hanga ana e ia tikanga ki te kohikohi anake te raraunga e ariā whakaaro ka hei te whai hua tino. Engari, i roto i te ao i reira e kua wātea mō te kore utu moni nui o ngā raraunga, hanga ana e ia te tikanga ki te tamata hoki he huarahi raraunga-tuatahi (Goldberg 2015) .

Ka rite ki kua whakakitea ahau i roto i tenei pene, ka taea e ngā kairangahau te ako i te rota e matakitaki iwi. I roto i te pene e toru i muri mai, ka whakaahua ahau pehea e nehenehe tatou e haapii atu, me te rerekē mea ki te faatano tatou i to tatou kohinga raraunga me te taunekeneke ki te iwi atu tika na roto i te ani ia ratou pātai (Chapter 3), rere ngā (Chapter 4), a tae noa wāhi ratou i roto i te tukanga rangahau tika (Chapter 5).
