Column Interpolation Add-In


-data table with a numeric continuous column containing some missing values.


The Column Interpolation Add-In will:


  • Bring up a dialog for column selection.
  • The selected column will be copied.
  • The original column will have it's missing values imputed by linear interpolation.

This script of this add-in was a patchwork of the following JMP Community conversations:






Why doesn't it work when I use it, it does not interpolate, but just copies a new column, and the missing values are not filled.

In addition, it would be great if more interpolation methods (such as polynomial interpolation, spline interpolation, etc.) can be implemented.


@wwh The new column appears to be a copy and the interpolated data is in the original column.
