Izibalo Zamastathistiki (STAT)

Ukuqalisa isibalo sezibalobalo, yenza lesi senzo (STAT) ukufaka Imodi ye-STAT bese usebenzisa isikrini esivelayo ukukhetha uhlobo lwesibalo ofuna ukusenza.

Ukukhetha lolu hlobo lwesibalo sezibalobalo:

(Ifomula yokubuyela emuva ibonisiwe kubakaki)

 Cindezela lo khiye:
Isimeleli-esisodwa (X) (1-VAR)
Isimeleli-esihambisana nesinye (X; Y), ukubuyela emuva komugqa

(y = A + Bx)

 (A+BX)
Isimeleli-esihambisana nesinye (X; Y), ukubuyela emuva kwe-quadratic

(y = A + Bx + Cx2)

 (_+CX2)
Isimeleli-esihambisana nesinye (X; Y), ukubuyela emuva kwe-logarithmic

(y = A + Blnx)

 (ln X)
Isimeleli-esihambisana nesinye (X; Y), e ukubuyela emuva kwe-exponential

(y = A eBx)

 (e∧X)
Isimeleli-esihambisana nesinye (X; Y), ab ukubuyela emuva kwe-exponential

(y = ABx)

 (A•B∧X)
Isimeleli-esihambisana nesinye (X; Y), ukubuyela emuva kwe-power

(y = AxB)

 (A•X∧B)
Isimeleli-esihambisana nesinye (X; Y), ukubuyela emuva kwe-inverse

(y = A + B/x)

 (1/X)

Ukucindezela noma ngimuphi ukhiye kwabangenhla ( ukuya ku-) kubonisa iStathistiki Editha.


Phawula

Uma ufuna ukushintsha uhlobo lwesibalo ngemva kokufaka Imodi ye-STAT, sebenzisa lo khiye (STAT/DIST)(Type) ukubonisa uhlobo lwesibalo esikrinini sokukhetha.

Ukufaka Idatha

Sebenzisa iStathistiki Editha ukufaka idatha. Sebenzisa okhiye abalandelayo ukuze obonise iStathistiki Editha: (STAT/DIST)(Data).
IStathistiki Editha inikeza imigqa engu-40 yokufaka idatha uma kukhona uhlu luka-X kuphela noma uma kukhona izinhlu zika-X no-Y, imigqa engu-20 uma kukhona izinhlu zika-X neze-FREQ, noma imigqa engu-26 uma kukhona izinhlu zika-X, Y, ne-FREQ.


Phawula

Sebenzisa ikholomu elithi FREQ (ukuvama) ukuze ufake ubungako (bokuvama) kwedatha yezinto ezifanayo. Ukubonisa ikholomu ethi FREQ kungakhanyiswa (ukuboniswa) noma kucishwe (ukungaboniswa) kusetshenziswa isethingi ye-fomethi ye-Stat kumenyu yokusetha.

Isibonelo 1: Ukuze ukhethe irigreshini ewumugqa ufake idatha elandelayo: (170; 66), (173; 68), (179; 75)

  • (STAT)(A+BX)
  • 170173179
  • 666875

Kubalulekile!

Yonke idatha efakiwe njengamanje kuStathistiki Editha iyasuswa noma nini lapho uphuma Kumodi ye-STAT, kushintshe kusukela kuhlobo lwesibalo sezibalobalo zesimeleli esisodwa kanye nezesimeleli esihambisana nesinye, noma ukushintsha isethingi ye-fomethi ye-Stat kumenyu yokusetha.

Izenzo ezilandelayo azisekelwe yiStathistiki Editha: , (M-), (STO). I-Pol, Rec, ÷R, kanye nezitatimende ezixubile nazo azikwazi ukufakwa kuStathistiki Editha.


Ukushintsha idatha yeseli:

KuStathistiki Editha, hambisa i-cursor kuseli elinedatha ofuna ukuyishintsha, faka idatha entsha, bese ucindezela .

Ukucisha ulayini:

KuStathistiki Editha, hambisa i-cursor emugqeni ofuna ukuwususa bese ucindezela .

Ukufaka ulayini:

KuStathistiki Editha, hambisa i-cursor endaweni ofuna ukufaka kuyo umugqa bese wenza isenzo esilandelayo:
(STAT/DIST)(Edit)(Ins).

Ukucisha konke okuqukethwe yiStathistiki Editha:

KuStathistiki Editha, yenza isenzo esilandelayo sokhiye:
(STAT/DIST)(Edit)(Del-A).


Isikrini Sesibalo Sezibalobalo

Isikrini Sesibalo Sezibalobalo ngesokwenza izibalo zezibalobalo ngedatha oyifaka ngeStathistiki Editha. Ukucindezela lo khiye kuyilapho iStathistiki Editha ibonisiwe, kushintshela Esikrinini Sesibalo Sezibalobalo.


Ukusebenzisa Imenyu Yezibalobalo

Njengoba Isikrini Sesibalo Sezibalobalo sibonisiwe, cindezela (STAT/DIST) ukubonisa Imenyu Yezibalobalo.
Okuqukethwe Kumenyu Yezibalobalo kuya ngokuthi uhlobo lwesenzo sezibalobalo esikhethiwe njengamanje lusebenzisa isimeleli esisodwa noma izimeleli ezihambisanayo.

  • Izibalobalo-Zesimeleli esisodwa

  • Izibalobalo-Zezimeleleli Ezihambisanayo

Isibonelo 2: Ukufaka idatha yesimeleli esisodwa x = {1, 2, 2, 3, 3, 3, 4, 4, 5}, usebenzisa ikholomu elithi FREQ ukubalula inani lokuphindkea kwento ngayinye ({xn; freqn} = {1;1, 2;2, 3;3, 4;2, 5;1}), kanye nokubala i-mean ne-population standard deviation.

Isibonelo 3: Ukuze ubale ukubuyela emuva komugqa nokubuyela emuva kokuhlangana kwe-logarithmic coefficients kwedatha elandelayo yezimeleli ezihambisanayo kanye nokunquma ifomula yokubuyela emuva kokuhlangana okunamandla kakhulu: (x; y) = (20; 3150), (110; 7310), (200; 8800), (290; 9310). Balula u-Fix 3 (izindawo zedesimali ezintathu) ukuze uthole imiphumela.

Ifomula Yokubuyela Emuva kwe-Logarithmic: y = -3857,984 + 2357,532lnx


Ukubala Amanani Asikiselwe

Ngokusekelwe kufomula yokubuyela emuva etholwe ngesibalo sezibalobalo zesimeleli esihambisanayo, inani elisikiselwe lika-y lingabalelwa inani elinikeziwe lika-x.
Inani lika-x elihambisanayo (amanani amabili, x1 no-x2, esimweni sokubuyela emuva kwe-quadratic) futhi lingabalwa nangenani lika-y kwifomula yokubuyela emuva.


Isibonelo 4: Ukunquma inani elisikiselwayo lika-x uma u-y = -130 kwifomula yokubuyela emuva ekhiqizwa nge-logarithmic yokubuyela emuva kwedatha Esesibonelweni 3. Balula u-Fix 3 ukuze uthole imiphumela. (Yenza isenzo esilandelayo emva kokuqeda izenzo Ezisesibonelweni 3.)

Kubalulekile!

Ukubuyela emuva kwe-coefficient, ukulungiswa kwe-coefficient, kanye namanani asikiselwayo wezibalo kungathatha isikhashana uma kunezinombolo ezinkulu zezinto zedatha.


Ukwenza Izibalo Zokwaba Okwejwayelekile

Uma isibalo sesimeleli esisodwa sezibalobalo sikhethiwe, ungenza isibalo esivamile sokusabalalisa usebenzisa imisebenzi eboniswe ngezansi kumenyu evelayo uma wenza isenzo sokhiye esilandelayo: (STAT/DIST)(Distr).

P, Q, R: Lezi zenzo zithatha impikiswano t futhi zinquma ithuba lokusabalalisa okuvamile njengoba kubonisiwe ngezansi.

t: Lesi senzo siqhutshwa ngempikiswano ka-X, futhi sinquma isimeleli esivamile Xt = X - xσx.
