# Weibull Distribution beta parameter

Good Morning,

I have been working on setting up the attached weibull analysis spreadsheet in Excel. My beta parameter result is 40 from the regression results . This seems unrealistic, I was wondering if someone could take a look at what is attached and let me know if I have an issue, or if the file contains reasonable results. Yes, this is the first time I've used Weibull analysis.

Thank you

Tommy,

Thanks for the observations. I didn't think that a beta parameter of 40 was valid.

As far as the column labels, take a look at this article:

The percentage thing is a frequency, we're actually trying to find the reliability of a process producing something 70% of the time.

Your Thoughts?

Thanks

Anything else you can provide would be appreciated - Thanks again.

Also, x is usually a time-to-failure, not a percentage.
