PPT-Multidimensional Scaling

Producing a map of distances from proximities Goals Given a matrix of proximities produce a map preferably two dimensional Fit is measured by stress how well the proximities data match the distances map. The compelling writings of Amartya Sen partic ipatory poverty exercises in many countries and the Millennium Development Goals MDGs all draw attention to the multiple deprivations suffered by many of the poor and the interconnections among these dep Bob Shackleton.
