Before revision:  The tool can be extended to monitor the progress of development of a regionover time, and to flag potential anomalies because of dissimilar outcomes due to different policy interventions in a geographic region by detecting sharp spatial discontinuities in the regression output .
After revision:  The tool can be extended to monitor the progress of development of a regionover time, and to flag potential anomalies . Finally, we use predicted variables to do robustness analysis of a regression study of high rate of stunting in India .
