**Indicator Parameterization Estimates** that does just that.

Re: In JMP, how to adjust the encoding of categorical variables in a regression model?

As far as I know, if you want to use dummy-coding instead of effect-coding in your models you will have to create the dummy-variables manually.

In most recent versions of JMP you can do so by "Cols=>Utilities=>Make Indicator Columns". Then use the dummy-variables as factors in your model (of course you should only use all but one).

Hope that helps.
