Given two data sets HAVE1 and HAVE2 above, is it possible to compute distance between each of the REPS  in HAVE1 with HAVE2 using FASTCLAUST--or any other SAS procedure? The distance is to formed  using variables A and B. The number of distance so derived will be equal to number of REPS in HAVE1. Since, the are 6 REPS, there should be six values of distances, signfigying distance from each of REPS in HAVE1 to the data set HAVE2.  

 

Thanks,

Re: Distance between clusters

PROC FASTCLAUST should perform K-means algorithm , therefore you can't guarantee it will split the data into two groups as your data showed, so you can't  get the distance by FASTCLAUST ,unless these two group data are apparetly different to each other.
