Hi All,
Is there any alternate procedure which will perform the same functionality of FASTCLUS? |

The FASTCLUS procedure performs a disjoint cluster analysis on the basis of distances computed from one or more quantitative variables. The observations are divided into clusters such that every observation belongs to one and only one cluster; the clusters do not form a tree structure as they do in the CLUSTER procedure. If you want separate analysis for different numbers of clusters, you can run PROC FASTCLUS once for each analysis. Alternatively, to do hierarchical clustering on a large data set, use PROC FASTCLUS to find initial clusters, and then use those initial clusters as input to PROC CLUSTER.

A quick Google search and review finds several pages related to SAS cluster analysis. SAS supports CLUSTER, FASTCLUS, VARCLUS, TREE according to what I can find.
You could also check out the SAS web site Use [URL] BBCode for External Links for specifics. |

Thanks for your response... I want to know an approach to convert the FASTCLUS statements to normal SAS statements.
If it is not possible, is it feasible to convert a SAS program to COBOL or Easytrieve? |

FASTCLUS statements are normal SAS statements -- just part of a PROC.
It is possible to convert a SAS program to COBOL but not always easy to do. I had a simple report program converted some years back and it took an experienced COBOL programmer over 2 months to convert the program from SAS to COBOL. A cluster analysis would be especially challenging in COBOL; I've had a year of college statistics plus a graduate class in statistics and I'd have to study the cluster analysis algorithm for a while before attempting such a program.
Perhaps if you explain what you're trying to do we can suggest alternate methods to achieve your goal? |
