Weibull paper in Excel - how?
 

Hi,

I want to create Weibull paper in Excel. The problem is the labelling
at the Y-axis.

I want to label probabilities (between 0.1 and 99.9%), but want to plot
the transformed logaritmic data; calculated out of the probability via
ln(ln(1/(1-p)))

X P (probabiliy, label) Y (transformed data; to
be plotted)
155 97,89% 1,350040182
325 97,61% 1,317875745
500 97,34% 1,288316244
525 97,07% 1,26088904


How can I do this either with or without VBA?

Has minitab this functionality included? Does it calculate beta and
eta?

thanks for the help,
Roger

In this example, I've used the normal distribution to generate a custom Y
axis. All you need to do is use your Weibull function. I've done this as
well, but I have no self-contained example.
