Subject: Question on Confidence
Message:
I am planning on conducting a reliability study using time censored data assuming a Chi-Square distribution. Assuming 0 failures, I have been estimating the appropriate length for the study to maintain a desired reliability and confidence. As I am limited on study length, I am considering lowering either confidence or reliability. Although I am reluctant to reduce confidence, it seams to be the option preferred by management to maintain a high minimum reliability. I am unclear on the effect of lowering confidence and was hoping someone could go into detail on the effect.
