Some new ado routines are available from ssc:

clustsens performs a cluster sensitivity analysis
        Cluster commands, especially when clustering on only a few variables can vary. 
        This routine investigates the range of that variation

optifact aids the task of creating the most optimum summated rating scale from a list of items.
        This routine looks at all possible combinations of items and lists the best scales
        that can be made from these items.  Performs canonical correlation and singular dimension
        checks for scales of equal k.

matsort sorts a matrix (required for the above routines)
