How do I enter a formula with parameters to be determined by the non-linear platform when there are several recursively defined column variables defined? In Excel, parameters are effectively global, but in JMP they are only local, so that it is not possible to estimate variables that are used in several column formulae. Alternatively, it does not seem possible to enter several recursive (parameter dependent) formulae in the one column. A simple example is when the next column variable depends parametrically on another, and vice versa for time-series data. Alternatively, perhaps I could bootstrap to find confidence limits for the non-linear parameters, but I do not know how to do that for the above example.
