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

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

      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:

    Hi sir, how to calculate the sample size for variable data?

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

    • @instituteofqualityandrelia7902
      @instituteofqualityandrelia7902  ปีที่แล้ว

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

      Hello Manikandboopathy, you may like to check the link onbiostatistics.blogspot.com/2017/07/bayes-success-run-theorem-for-sample.html. Similar information is available on other web sites. Hope this helps.

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

    • @instituteofqualityandrelia7902
      @instituteofqualityandrelia7902  2 ปีที่แล้ว

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

    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.
