No longer able to find the Shapiro Wilk testHi,
I am suddenly unable to find the Shapiro wilk test when assessing data for normality. I used to use the distribution --> continuous fit --> normal --> then goodness of fit (which was shapiro wilk by default if i remember correctly)
Now i dont get 'normal' as an option, instead i get' fit normal' and then the goodness of fit test is Anderson- Darling.
Any idea what happened?
Thanks.
Re: No longer able to find the Shapiro Wilk testThank you very much for your quick reply and screenshots. I had done those steps and it still wouldn't work. I even reset the platform preferences to defaults just in case there was some bug. I was going crazy until I realized my sample was >2000, in which it would default either to the Anderson-Darling test only (through the new fitter, even when legacy fitter had been enabled) or the KSL test (if done via the legacy fitter). If I decrease my sample to below 2000, it works. Thanks again.

The Shapiro-Wilk test was added to the new fitter along with the Anderson-Darling test in the JMP 15.1 maintenance release.
Re: No longer able to find the Shapiro Wilk test
Distribution>Continuous Fit>Enable Legacy Fitters>Legacy Fitters>Continuous Fit>Normal>Goodness of Fit
This is from JMP 15.1
Re: No longer able to find the Shapiro Wilk testHi,
Even after enabling the legacy filters and going to
Legacy filters ====> Continuous fit
The Shapiro-Wilk option does not show up and if if you run Normal, the KSL test result is displayed. No other Goodness of Fit option under legacy filters. See attached image. (JMP 15.1.0 Pro)
Re: No longer able to find the Shapiro Wilk testThis answer was provided @txnelson....
The Shapiro-Wilk test has deemphasized and moved to being a legacy statistic. To gain access to it, run the Distribution Platform. Under the red triangle for the Column being analyzed select
Continuous Fit==>Enable Legacy Fitters
Then go back to the red triangle, and the new selection option will appear
Legacy Fitters==>Continuous Fit
The Shapiro-Wilk test will be displayed when you select the Goodness of Fit under the Legacy Fitters
