Im using the non-parametric binomial equation, found in the link here https://reliawiki.org/index.php/Reliability_Test_Design
It is written below:
1−C=∑(i=0 to f)(n,i) ((1−R)^i)*R^(n−i)
Where C is the confidence level, f is the amount failures R is the reliability n is the amount of samples
I am trying to solve for n, when the amount of failures = 1
I have solved for n, when failures = 0, but when failures is 1 the equation takes a shape im not familiar with.
Is anyone familiar with solving this equation?
Thanks,
