Isibali-migaqo kaKelly
Imigaqo kaKelly ibeka isabelo semali yakho yokubheja esonyusa ukukhula kwexesha elide. Ngamathuba angama-55% kumathuba alinganayo, yi-10%; ngaphandle kwenzuzo, ngu-zero, kwaye ukubeka isabelo esiphindwe kabini kwekaKelly akukhulisi imali yokubheja ngokukhawuleza kunokungabheji kwaphela.
Indlela esebenza ngayo
- Isabelo sikaKelly = (b × p - q) / b, apho b = amathuba e-desimali - 1, p ngamathuba akho okuphumelela kwaye q = 1 - p.
- Ukukhula okulindelekileyo ngokubheja = p × ln(1 + b × f) + q × ln(1 - f) kwisabelo f semali yokubheja. UKelly opheleleyo uyenza ibe nkulu kakhulu: 0.50% ngokubheja kumzekelo.
- UKelly oqingatha ugcina 75% yolo khula ngokutshintsha okuncinci kakhulu, yiyo loo nto ababheji abaninzi besebenzisa inxalenye.
- Yonke into ixhomekeke ekubeni amathuba akho achaneke. Inzuzo eqikelelwe ngokugqithisileyo yenza isabelo sikaKelly sibe sikhulu kakhulu, kwaye isabelo esikhulu kakhulu sinciphisa imali yokubheja ngokomndilili.
