    It would be great if you can also explain where does Chi-square formula come from.

    Hi, can i ask why 1-CL = cumulative binomial equation? What does 1-confidence level means in reliability demonstrates tests? Thanks

      Hello! Apologise for late reply. 1-C means probability of those many failures. Confidence level is 1-probability of those many failures.

    Why in the first case is using the non parametric test and then uses the binomial method?

    Hi Sir.....Is there any reference on how the formula derived from ? If not mistake is from Binomial Distribution . I used this method to determine sample size . However FDA required a proper reference on the method used .

      You can get referrences on internet. Here is one: stats.stackexchange.com/questions/73645/how-do-you-derive-the-success-run-theorem-from-the-traditional-form-of-bayes-the.

    these many samoles to be used fot any type of samole testing? prst or fixed?

    • @instituteofqualityandrelia7902
      @instituteofqualityandrelia7902  11 місяців тому +1

      No. Not for any type of testing! This is generally for one shot devices and no failure. In PRST or Fixed length plans allow failures and estimate MTBF.
      Watch these videos on Reliability sampling trst plans for more details:

    With the sample size of 240 (N) in a qualitative study what method should we apply for the reliability test?

    • @instituteofqualityandrelia7902
      @instituteofqualityandrelia7902  Рік тому

      If all are successes, use Success Run theorem. If you have failures, then you need to calculate probability using Binomial or approximate normal distribution.
