Iindlela Uhlalutyo lwezoqoqosho lweshishini - ngencukatha ezithe

Uhlolo esemgangathweni umsebenzi yezoqoqosho kweziphumo lweshishini kukudliwa uhlalutyo loqoqosho. Kulo mzekelo, iingqiqo ezimbini Uhlalutyo lwezoqoqosho kufuneka ukwahlula ngokucacileyo: "Indlela" yaye "iindlela".

Indlela ithathwa kuba kukuyilwa imodeli ubudlelwane phakathi kwezalathisi kunye nezinto ezichaphazela ezi ziphumo.

Mu kuya kwa nshita indlela, iindlela Uhlalutyo lwezoqoqosho igalelo lihlolisisa yacwangciswa yempembelelo yeemeko ezithile phezu impumelelo yokusebenza lweshishini, kulandele gabalala yeempawu ifunyenwe.

Njengesixhobo, ngokuyintloko wasebenzisa indlela ekhethekileyo lwezalathisi eziphawula umsebenzi kuqoqosho lweshishini kwaye nokuphucula ukusebenza yemveliso.

Iindlela eziphambili Uhlalutyo lwezoqoqosho lusekelwe kulwazi Sciences ezisisiseko ezifana ezoqoqosho, amanani nakwimathematika.

ekunokuthiwa iindlela zoqoqosho:

- kudweliswe iimpawu ezifanayo isifundo kolwalamano ngezenzeko entsonkothileyo;

- uthelekiso, uqhutywe ngokuthelekisa data yacazululwa;

- ukulingana indlela, esakhiwa ngo ngokuthelekisa amanani amabini, awazise kwibhalansi eqhelekileyo;

- indlela lomzobo.

iindlela statistical Uhlalutyo lwezoqoqosho kubandakanya ukusetyenziswa kwezi ndlela:

- amaxabiso isihlobo (ipesenti womxhuzulane ethile, isalathiso lomlingani) - amanani avareji;

- Umahluko elililo - isiphumo utshintsho zibalwe imveliso unxaxho kwezi zibakala yacazululwa yaza baseline (okanye ingxelo) amaxabiso factor yesibini;

- esikhundleni chain, obonelela ekubaleni isalathiso lilonke ixabiso eliphakathi ngokokubekwa chu amaxabiso esisiseko nezikhombisi zale ngxelo.

Kuba iindlela manani uhlalutyo loqoqosho, ngaphandle kwabo badweliswe ngasentla, ukuba lomlingani kunye index neendlela, ukwakhiwa eziliqela iinguqulelo ka. indlela lomlingani lisetyenziswa kwi kuhlalutyo kwezoqoqosho, kunye uhlalutyo factor kwaye thaca inkqubo lwezibonisi isalamane iingxelo zemali (ikakhulu nebhalans-shithi ingeniso ingxelo ilahleko).

indlela Index isekelwe phezu kwezi zithethe zixabisekileyo isihlobo, kumiselwa ukuzalana data eyiyo kwi kwithuba accounting, inani ahambelana kwexesha ezisisiseko (okanye, kuba acwangcisiweyo).

Indlela parameter nganye kunye nohlalutyo ukuhlanganisa esetyenziswa manani nakwimathematika. Nokusebenzisa kwayo ubuhlobo uzimisele phakathi izikhombisi azikho ukuxhomekeka esebenza.

iindlela Mathematical ziquka iinkqubo zemathematika, ngumzekelo (matrix calculus, ithiyori ye eseleyo igalelo-ifayileyemveliso) kunye neendlela zophando ezahlukeneyo (umzekelo, umdlalo).

Uhlalutyo lwezoqoqosho ithathwa ngokuyintloko uhlalutyo factor. Uhlalutyo factor inika inguqu ukusuka ekuqaleni inkqubo into ethile lokugqibela (ezinqwenelekayo) inkqubo impembelelo. Xa oku kwenziwe Utyhila intlanganisela ngokupheleleyo ezinokuphembelela abe iqondo elikhulu okanye elingezantsi nempembelelo kwiziphumo yemali yenkampani.

Zonke ezi ndlela Uhlalutyo lwezoqoqosho zingasetyenziswa ngokusebenzisana ucazululo epheleleyo imisebenzi iqumrhu loshishino. Zisuka nje, ukuba uhlalutyo lweengxelo zemali ezisetyenziswayo ngokwamaqela indlela parameters, uthelekiso kwezi zalathisi kunye nokumelwa kwabo lomzobo. Kodwa ke ukufunda lweepateni yophuhliso iinjongo zihlalutywe ikhutshwa phandle usebenzisa iindlela manani xa kuhlalutywa ixesha series.
