Resumen
The median rank function F(i,n) is used to estimate the cumulative probability of failure of the i-th of n identically stressed samples. There are several simple formulas proposed by Weibull and others [1] that give approximate values for the median rank.
The exact median rank function F(i,n) is related to the incomplete beta function Bx(a,b), which is hard to calculate. Jacquelin [2] recommends an algorithm based on the Newton-Raphson method.
This Demonstration presents the exact median rank using Jacquelin's method and plots it in different ways Componente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemática
