Isicelo sesitatisti ngokurhweba ngemali. Ukuphambuka okuMgangatho

Nguwuphi umrhwebi ongeke afune ukwazi ukuba ukuphakanyiswa kwemali ekhethiweyo yoshishino kunokunyuka okanye kwehla? Ewe, asikwazi ukujonga kwixesha elizayo kwaye sikufumanise ngokuqinisekileyo oku, kodwa kulo mzekelo uncedo olungenako lunikwa ngeenkcukacha. Ukwazi ukuba isalathisi esikhethiweyo sitshintshile njani ngaphambili, kunokwenzeka ukubala ngezinga eliphezulu lokuzithemba iqondo lokutshintshwa kwalo kwikamva. Kwaye apha apha isibonakaliso sokuphambuka okuqhelekileyo kuya kusinceda. Esi sibonakaliso siyaziwa nangokuphambuka okuqhelekileyo, ukuphambuka okuqhelekileyo, ukuphambuka kwe-quadratic.

Ukuphambuka okusemgangathweni yenye yezona zikhombisi ezisetyenziswa ngokubanzi kwiinkcukacha kunye neendlela ezinokwenzeka. Ibonisa umlinganiselo wokusabalalisa ukuguquguquka okungahleliweyo ngokubhekiselele ekulindelekeni kweemathematika. Le nombolo iboniswe kwiiyunithi ezifanayo njengoluhlu oluthile. Cinga indlela onokumisela ngayo ukuphambukiswa okuqhelekileyo. Ifomula yokubala esi sixalisi ilandelayo:

STD = √ [(Σ (Х-Хср) 2) / n], phi

I-STD kukuphambuka okuqhelekileyo,

√ [] yinto engcambu,

I-Xp iyona xabiso eliqhelekileyo leparameter phantsi kokufundwa kwenani le-n-th lexesha,

N lilonke inani lexesha lexesha.

Xa kubalwa ukuba kuyimfuneko ukuqwalasela i-nuance eyodwa. Ukuba n> 30, n-1 isetyenzisiwe njengenxalenye yeqhezu.

Ukubalwa kokuphambuka okuqhelekileyo kwenziwa ngokufanelekileyo usebenzisa i-Excel yesicelo, ngoku sele ifakwe kwiikhompyutha nganye. Ukwenza oku, sebenzisa ifom ye-STDEV ekwakhiwe.

Ngoku makhe sithethe malunga nendlela ongayisebenzisa ngayo le nqondiso kwizorhwebo. Ukuphambuka okuqhelekileyo kuyinxalenye yezibonakaliso zobugcisa ezakhiweyo kwisigxina esithandwayo seMetrareder, kwaye sibonisa amandla okunyuka kwexabiso ngokumalunga nomyinge ohambayo. Kwimeko apho ixabiso layo lifikelela kwisigxina esilandelayo, oku kuthetha ukuba okwangoku i-maritime ibonakaliswa ngokunyaniseka okukhulu kwaye intengo yesicatshulwa ichithwa kakhulu kwixabiso eliqhelekileyo. Ukuba isibonakaliso sifinyelela ubuncinci, ngoko imarike ilindele, kwaye amaxabiso emijelo ayesondele kakhulu ekulindeni kweemathematika. Ekubeni imakethe ye-Forex ibonakaliswa ngokutshintshana okulandelelana kwemisebenzi kunye nokuzola, esi sibonakaliso singasetyenziselwa ukuqikelela ixesha elizayo.

Ngoko, ukuba kuncinci, ngoko kungekudala kuya kubakho ukunyuka komsebenzi kwaye ixabiso lentengo litshintshe ngokuphawulekayo. Ngokuqhelekileyo oku kwenzeka ngaphambi kokukhululwa kweendaba ezibalulekileyo okanye xa kunokungaqiniseki kwiimarike, kwaye akukho zinkomo ezingenayo zikwazi ukufezekisa inzuzo. Ngeli xesha kungcono ukulungiselela ukuvulwa komyalelo ngokukhawuleza emva kokuba ulandelelwano olongezelelweyo lwentshukumo yentlawulo lube lucacileyo, okanye luvule i- oda kulindile zombini kwaye ulinde de kube enye yazo isebenze kwaye ivale enye yesibini.

Ukuba isibonakaliso siqala ukuphuma esikolweni, kuthetha ukuba imisebenzi yabatyalomali iya kudala, kwaye kufuneka ucinge ngezikhundla zokuvala, kungekudala ukulungiswa okanye ukuguqulwa kungenzeka.

Ukuphambukiswa okuqhelekileyo kufakwe rhoqo kwezinye iisalathisi. Umzekelo obalaseleyo wale mizila yeBollinger, apho eli xabiso likunikwa ukucacisa imida ephezulu nangaphantsi yokuhamba kweengcaphuno. Le mida, kunye nomgca ophakathi, isebenza njengezinto ezihlukeneyo zokuxhasa kunye nokuchasana. Ngoko ukuba ixabiso lichanekileyo ngaphezu komyinge, ngoko kulindeleke ukuba lifikelele kumda ophezulu, kwaye ngokuphambene, ukuba kuluhlu olungaphantsi, luya kuthatha umgca weBollinger ophantsi.

Umgca ophakathi kwalomqondiso ubonisa ulwalathiso namandla omoya. Eyona mgca umgca lo mgca wenza kunye ne-X axis, ngakumbi amandla omoya. Ngeli xesha, ukuphambuka okuqhelekileyo kuyaqala ukwandisa. Kodwa ukuba iya kuba yinto efana ne-axis ene-horizontal axis, ke oku kubonisa ukunyuka komgangatho, izinga lokusabalalisa liyancitshiswa, kwaye i-marhwebo iya kwiimeko zokuphumla okanye ukulindela kwesinye isiganeko esibalulekileyo.
