Calcualtes the confidence that we've met the reliability requirement

Description

exp_rel_conf calculates the confidence that we've met the reliability requirement (the true MTBF exceeds the MTBF requirement), assuming that the times between falilure are exponentially distributed.

Usage

exp_rel_conf(mtbf_req, duration, r)

Arguments

mtbf_req	A numeric vector indicating the MTBF requirement.
duration	A numeric vector indicating the tested duration (hours, miles, rounds, etc.).
r	A numeric vector indicating the observed number of failures.

Value

The output will be a numeric vector, indicating the confidence that the MTBF requirement was met.

Examples

# How much confidence do we have that the MTBF exceeds 250 hours, given
  # that we tested for 500 hours and observed 0 failures
exp_rel_conf(250, 500, 0)
