Multivariate kernel density estimator in JMP

I would like to obtain a column with the denisity of the points using a kernel density function.

 

In 1 D, it will be something like histograms:

Comparison of the histogram (left) and kernel density estimate (right) constructed using the same data. The 6 individual kernels are the red dashed curves, the kernel density estimate the blue curves. The data points are the rug plot on the horizontal axis.

https://en.wikipedia.org/wiki/Kernel_density_estimation

 

Densities can be visualized in the graph builder, and calculated for 1 dimensional data. But I wonder how to do that systematically for multivariate data (more than one dimmension).

See Help > Scripting Index. Search on 'kernel.' I found this function that could be used to populate a column:
