Kuwirirana uye regression ongororo yaro yakafara chikumbiro ari upfumi

Basic Statistical nzira yagara kushandiswa zvose okukurukura mabasa evanhu. Zvisinei, chinonyanya kukosha basa reDare nhamba iri upfumi. Pashure pezvose, bazi iri nesayenzi inodzora ukama socio-mune zvemari basa masangano mubasa Kuongororwa uye kubudiswa hombe yakawanda mashoko.

Kakawanda muzvidzidzo zvoupfumi kuwana chinetso kuona zvinhu kuti kuona padanho kwacho emuchina vari upfumi. Kazhinji dambudziko kwakadaro anodzidudzira kuwirirana uye regression kuongorora. Kuti vabudirire rakavimbika kuongorora zvakafanira kwete chete kuziva zvimwe ukama, asi kuti uwandu zviratidzo izvi.

Kuwirirana uye regression kuongorora anogadziriswa dambudziko iri, sezvo nomuedzo Statistical pfungwa pamusoro kuvapo uye nesimba kuwirirana. Yakakwana zvinoverengeka kukanganisa kwacho upfumi, havasi anongoitika variables. Chokwadi ichi kushanda chinodiwa kuti ari kuongorora zvoupfumi mananara vari zvoushumiri ukama pakati asingashumbi uye non-chero tsika. zvokufambisa izvi dzinonzi regression uye saka ari Statistical nzira, iyo inodzidza kwavari - regression kuongorora.

Nokuda chichiitwa kukura noruzivo rwemakombiyuta, kushandiswa kwemichina kombiyuta iri kuwedzera kushandiswa Statistical Masvomhu. Saka, kushandisa dzimwe kombiyuta Statistical date kubudiswa Software unokubvumira nokukurumidza zvinetso pamusoro ukama parameters siyana achishandisa regression kuongorora.

Saka, kuwirirana uye regression kuongorora (muenzaniso uri) zvakakwana chinoratidza kushandiswa kwayo Microsoft Excel chirongwa kana processing date Exchange.

Microsoft Excel The Toolkit unokubvumira kugadzirisa zvakaoma Statistical uye ouinjiniya matambudziko vachishandisa chaiyo akagadzirwa date ongororo Ezvemutauro. Kuwirirana uye regression kuongorora muna Excel rinoitwa pamwe kwairayirwa chinoratidza mazano Data uye kusarudza kutanga parameters. Analysis pachayo iri kuitwa kushandisa Statistical makro (iripo youinjiniya basa), mugumisiro anoiswa mukati goho siyana kuti zvinogona kutaurwa ne user. Kana ukashandisa dzimwe nzira papurogiramu, tinogona kuwana kwakaguma graphical chimiro.

Achibatsirwa munhu hwakajeka mufananidzo muongorori kuona kutarisana kumiririrwa Statistical mashoko. rudzi urwu hwezvekukurukurirana zvikuru maonero uye kunzwisisa zvabuda.

Somuenzaniso, apo kuvhenganisa tafura nhamba iri dzimwe nguva zvakaoma kuziva zvikanganiso kana mashoko okuti. Nomufananidzo somunhu date girafu unokubvumira nokukurumidza uye nyore nyore kuona zvarakasiya uye anomalies, rakapinza kuwedzera kana donhwe data, kunyange tafura asingadi chinorevei zvakadaro zvinhu zvisingafadzi.

Kuwirirana ari Microsoft Excel chishandiso pasuru. Inogona kushandiswa uwandu hwazvo ukama anoverengeka mashoko seti. Kuwirirana kuongorora anogona kumisa ukama iri kukosha kwakaita mashoko seti. Saka, pane pfungwa "zvakanaka" kuwirirana (dzakakwirira tsika humboo mumitsetse kunoenderana chete guru tsika imwe vakarongedza), kuti "akaipa" kuwirirana (diki ukoshi mumwe date faira chokuita tsika vemamwe mumitsetse) uye kuwirirana vakaenzana razero (date ari arrays vaviri hazvina kubatana). Regression kuongorora muna Microsoft Excel iri vakaronga kushandisa Statistical nzira yakadai zvinenge dzinoungana.

Saka, kuwirirana uye regression kuongorora zviri nyore zvikuru kuti tiite nokushandiswa kombiyuta yemazuva ano, vachibvumira kuwana zvinodiwa kunoguma pfupi nguva.
