UKUFANELEKELA KWE-CARVE KUSEBENZISA UKUHLELI OKULAyini FUTHI OKUNGEYOKUGQUGQUZELA
I-Multiple Regression calculator iyithuluzi elifanele ijika lokuxazulula izibalo ezinezixazululo eziyisithombe. Lolu hlelo lokusebenza lokubala lokuhlehla lwakha ijika noma ifomula yezibalo isebenzisa izindlela eziyisikwele okungenani. Ikusiza kuzibalo zomugqa wezithombe kanye nezibalo ezingaqondile ukuze ufunde izibalo nokuziphatha kwamajika ochungechungeni olunikeziwe lwamaphoyinti edatha.
Ukuhlehla kuyindlela ewusizo yezibalo ekuvumela ukuthi ulinganise futhi uhlole ubudlelwano phakathi kokuhluka okuncikile kanye nokuhluka okuhlukile okukodwa noma ngaphezulu. Lesi sibali segrafu esilingana nejika sinezinhlobo ezahlukene zokuhlehla kwezibalo ukuze kuxazululwe izibalo zamagrafu kanye nezinkinga zezibalo phakathi nendaba yamasekhondi.
Kunamamodeli ahlukene okuhlaziya ukuhlehla okufana ne-polynomial, exponential, half life, reciprocal, gaussian, njll. Nokho, lolu wuhlelo lokusebenza lokuhlela igrafu olusha lwabafundi bezibalo, onjiniyela, abahleli bezinhlelo zokufunda ngomshini nososayensi bedatha. Ngaphezu kwalokho, ungasebenzisa lesi sibali segrafu yesakhiwo sejika ezilimini eziningi, okuhlanganisa isiNgisi, iSpanishi, isiFulentshi, isiNtaliyane nesiJalimane.
INDLELA YOKUFAKA IDATHA:
x=1,2,3,4. noma x=-1,-3,0.5,1
y=1,2,3,4     noma y=-1,-3,0.5,1
Ungasebenzisa amanani amaningi ka-x kanye no-y ngokuthanda kwakho (faka amaphuzu edatha angenamkhawulo),
Ungabuka idatha yakho ukuze ukhethe imodeli efanele yokuhlehla.
Amamodeli Okuhlehla
I-multiple regression calculator ikuvumela ukuthi wenze ukuhlaziya kwezibalo kulawa mamodeli

• Imodeli egqamile (ae^bx)


• Imodeli ye-Polynomial (a_n x^n+a_(n-1)+.....+a_0)


• Imodeli yamandla x (ab^x)


• Imodeli yamandla b (imbazo^b)


• Imodeli ye-Logarithmic (log(x+b)+c)


• Imodeli ye-Gaussian (ae^-(x-b)^2/(2c^2))


• Imodeli ye-Half Life (a+b/2^x)


• Imodeli ehambisanayo (a+b/x)


• Imodeli kaMichaelis (izembe/(x+b))

== Faka Isethi Yakho Yedatha
Uma ufuna ukulingana nedathasethi yakho kumazibalo afana ne-Exponential, Power, Half-life, Michaelis Mentent(Plateau), namajika e-Gaussian, udinga ukunikeza uhlelo lokusebenza ngedathasethi ethi x kanye no-y, bese uchofoza inkinobho ehambisanayo (Ukuze uthole Amandla ijika, cindezela inkinobho yokulinganisa amandla)  (igrafu yokuhlehla komugqa, ukuhlehla okungaqondile, ukuhlehla komugqa okuningi, ukuhlehla kwe-polynomial, isibali sokuhlehla kwe-quadratic). Uma ufuna ukulingana idathasethi yakho ku-Linear noma i-Polynomial curve, kuzomele unikeze uhlelo lokusebenza ngezinga le-polynomial; ngejika elilayini, idigri i

ULUSEBENZISA KANJANI UHLELO LOKUSEBENZA?
LAISHA: Inkinobho yokulayisha ikuvumela ukuthi ufunde amafayela e-CSV edatha yakho agcinwe ocingweni lwakho noma kwisitoreji sekhadi le-sd. Idatha izobhalwa ngefomethi yefayela le-CSV.
BUKA: Lapho ugcwalisa izinkambu u-x no-y ngedatha yakho, chofoza inkinobho ethi BUKA ukuze ubone ukuhlobana phakathi kwedatha ka-x kanye no-y.
Khetha Imodeli: Ngemva kokubuka idatha, khetha imodeli efanelekile engalingana nedatha yakho ohlwini olutholakalayo lwamamodeli.

FIT: Ngemva kokukhetha imodeli ohlwini olutholakalayo, chofoza okuthi FIT ukuze ulingane idatha yakho nemodeli ekhethiwe. Ngemva kwalokho, uzoyiswa kwelinye ikhasi lapho uzobona khona imodeli yokuhlehla. Izobonisa i-coefficient ye-determination R-square.
Ungakwazi ukulinganisa imodeli efakiwe ngamavelu ahlukene ka-x ngokufaka inkambu ethi xe bese uchofoza inkinobho ethi Linganisa ukuze ubonise umphumela kunkambu ye-ye.
LONDOLOZA: Cindezela inkinobho yokulondoloza ukuze ulondoloze idatha yakho, imodeli efakiwe, imodeli elinganiselwe ngamavelu anikeziwe angu-x, u-r-square kanye nephutha lemodeli elondolozwe njenge-CSV noma amafayela e-txt kusitoreji sefoni yakho njenge " model_regression.csv" noma "model_regression.txt" igcwalisa ifolda ebizwa ngokuthi curve_fitting_data

IZICI ZOKUSEBENZA:

• Isixhumi esibonakalayo esisebenzisanayo nesigxile kumsebenzisi


• Yakha ijika noma umsebenzi wezibalo


• Ivumela ukungenisa noma ukuthekelisa idatha yakho


• Sebenzisa izindlela eziyisikwele ezincane zokuhlehla


• Isibali sezibalo esisebenza ngokunembile


• Ifaka amamodeli amaningi wokuhlehla ukuze kuxazululwe izibalo
