Re: Weibull Plot With Minitab
Well if your running reliability you are not limited to a Weibull distribution. You may find a better distribution based on your data, or example studied.
Check the stat menu go down to reliability.
If the data is right censored (failure times) then use the distribution analysis right censored.
If it is in intervals use the arbitrary censoring choice.
The ID plot choice will try and fit different distributions to your data to give an idea of which fits best.
The overview plot gives a graphical 4 graphs on page display of the Hazard and survival.
The parametric distribution analysis will allow you to get large tables of percentiles and survival times. Using some of the options like estimate you can enter particular survival times or percentiles to get PI's and CIs out.

Reason: Corrected interval choice to arbitrary censoring
