Art of Stat: Regression

I-Art of Stat: Uhlelo lokusebenza lwe-Linear Regression ludala ama-scatterplots, alingana amamodeli alula (futhi amaningi) alayini, aphathekayo noma ohla lwe-exponential, futhi lubonisa inkomba yemingcele yemodeli (amaphutha ajwayelekile, izikhawu zokuzethemba, amanani we-P).

Okusha: Uhlelo lokusebenza manje luphinda lulingane namamodeli amaningi omugqa wokuhlehla futhi luvumela okufaka phakathi izibikezelo zezigaba nokusebenzisana kwezindlela ezimbili!

Uhlelo lokusebenza lubala futhi lubonise izikhawu zokuzethemba zempendulo emaphakathi nezikhawu zokuqagela zempendulo yesikhathi esizayo. Imodeli efakiwe kanye nezikhawu ziboniswa ku-scatterplot, futhi ungathola futhi uhlele izinsalela ezingavuthiwe nezijwayelekile.

Ungafaka imibala kumaphoyinti ku-scatterplot ngokuya ngokuhlukahluka kobuningi besithathu noma ngokwezigaba ukuze uveze amaphethini engeziwe.

Ukuze ufake idatha, ungafaka eyakho idatha ngohlelo lokusebenza olusha lwe-Data Editor, ungenise ifayela le-CSV, noma ukhethe kumasethi edatha ayisibonelo alayishwe ngaphambilini.

Izici:

- I-Scatterplot Matrix ukutadisha ubudlelwane obubili

- Bonisa isibalo sokuhlehla esifakiwe ku-scatterplot, ngisho noma kufaka (nokwengeziwe) isibikezelo sesigaba

- Ithebula elinawo wonke ama-coefficients okwehla kanye nezinkomba zawo (amanani e-P, izikhathi zokuzethemba)

- Izibalo ezifingqiwe ezifana ne-R^2, R^2-elungisiwe futhi yakhulisa ukungena ngemvume

- Amanani afakiwe kanye nezinsalela (ezijwayelekile) (ongazilanda)

- Izibikezelo zamanani akho wezinto eziguquguqukayo ezichazayo

- Isakhiwo esisele sokuhlola ukucabanga kanye nezangaphandle

- ikuvumela ukuthi wenze izibikezelo zamanani akho wezinto eziguquguqukayo ezichazayo

- wakha isakhiwo esiyinsalela ukuze ahlole okucatshangwayo kanye nezinto ezingaphandle
