Kusuka embhalweni onikeziwe, ngichazele imininingwane ephathelene ne-parity plot
Context:I-parity plot iyi-scatterplot eqhathanisa isethi yemiphumela evela kumodeli yekhompyutha nedatha yokulinganisa. Iphuzu ngalinye linezixhumanisi (x, y), lapho i-x iyinani lokulinganisa futhi i-y iyinani elihambisanayo elivela kumodeli.  Umugqa we-equation y = x, omelela ukusebenza komodeli okuphelele, ngezinye izikhathi ungezwa njengereferensi. Lapho imodeli iphindaphinda ngempumelelo inkomba, lelo phuzu lizoba kulayini.  Izithombe zokulingana zitholakala emaphepheni nasemibikweni yesayensi, lapho umbhali efisa ukuqinisekisa imodeli ngendlela ebonakalayo. Nokho, lapho idatha inebanga elibanzi, isikali esikhulu senza ukungafani okubalulekile kungabonakali futhi imodeli ibonakale ingcono kunalokho eyikho ngempela. Kuleso simo, i-plot yamaphutha omodeli [(y-x) vs. x] ingcono ekuhloleni ukusebenza komodeli.
1. Izinkomo I-parity plot iyi-scatterplot ehlukanisa okuphuma kumodeli yekhompyutha nedatha eyisithenjwa. 2. Izingelosi Iphuzu ngalinye likhonjwa nge-coordinates yalo (x, y), lapho i-x imele inani lokulinganisa futhi i-y iyinani elihambisanayo elivela kumodeli. 3. Izingelosi Ukuze kusetshenziswe njengereferensi, ngezinye izikhathi kufakwa umugqa odwetshwe ku-equation y = x. Lapho imodeli iveza ngokunembile inkomba, lelo phuzu lizowela kulayini. 4. Izidakamizwa Lapho umbhali efuna ukuqinisekisa imodeli ephepheni noma embikweni, kusetshenziswa iziza zokulingana. Ngakolunye uhlangothi, lapho idatha ihlanganisa ububanzi obubanzi, isikali esikhulu sifiphaza umehluko obalulekile, okwenza imodeli ibonakale ingcono kunalokho eyikho ngempela. Kulesosimo, i-plot yephutha lemodeli [(y-x) vs. x] iyathandeka ekuhloleni ukusebenza kwemodeli.
