How to calculate reliability growth parameter standard errors?<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />I am looking to know the formula to calculate the standard errors for reliability growth parameters lamda and beta.
Re: How to calculate reliability growth parameter standard errors?Thank you, Michael. I will review this article.
Re: How to calculate reliability growth parameter standard errors?I think this paper might help:
Crow, L. H., (1982), “Confidence Interval Procedures for the Weibull Process with Applications to Reliability Growth,” Technometrics, Feb. 1982, 24:1, 67-72.
Re: How to calculate reliability growth parameter standard errors?Thank you, Michael. I did find the passage to which you are referring. I am actually looking for the math that is used, which is not in the provided link. Is there an article or book you can refer me to?
Re: How to calculate reliability growth parameter standard errors?This is described in the Statistical Details section of the Reliability Growth documentation:
Statistical Details for the Reliability Growth Platform
Re: How to calculate reliability growth parameter standard errors?The covariance matrix for the parameters is estimated using the Fisher information matrix. Although, using MS Excel, I cannot get the estimates to match exactly. They look to be the same up to 2 decimal points.
