The function for calculating the probability of passing critical quality attributes (CQA) specification test .
rl_pp(Llim, Ulim, mu, sigma, NV)
| Llim | lower specification limit |
|---|---|
| Ulim | upper specification limit |
| mu | hypothetical mean of the attribute |
| sigma | hypothetical standard deviation of the attribute |
| NV | nominal volume for the specification test. |
A numeric value of the passing/acceptance probability
