Arguments

`x`	number of successes (integer between 0 and n inclusive)
`n`	number of binary trials
`a`	coverage error of limit

Value

A numeric value between 0 and 1

Examples

# Find exact 99% lower limit for probability based on 20 successes from 55 trials.
CP.lower(20,55,a=0.01)
# Find exact (95%) lower limit for probability based on all failures.
CP.lower(0,5)
