How do I fit a normal 4 mixture to a distribution?

[#1]

I frequently deal with multimodal distributions in my data. Usually they are straightforward normal 2 or 3 mixtures, but occasionally I have more modes. It must be possible to fit more than 3 normal mixtures. I have an example from some older work where JMP has produced exactly the kind of normal 4 mixture that I now need to do. I'm attaching this example. I'm using JMP Pro 17.0.0 - can anyone point me to how I can generate the kind of normal 4 fit that you see in the attached example?

Not sure if there are other places where you can do this, but enable legacy fitters

and then you get new menu where you can use Normal Mixture Other

Thanks! This works perfectly. Wonder why JMP makes this so hard to find and doesn't seem to have it in their documentation. However, you have gotten me to the right place, so thanks again.

You could use Life Distribution for this purpose.

The reply by jthi above is exactly the solution. Thanks.
