... The routines implemented are CLUSTER which has 8 options for hierarchical clustering and PARTITION which carries out non--hierarchical clustering. ... The former is non--hierarchical clustering or partitioning. The latter is hierarchical clustering. Brief consideration will show that a sequence of n-1 agglomerations are needed to successively merge the two closest objects and/or clusters at each stage, so that we have a set of n (singleton) clusters, n-1 clusters, ..., 2 clusters, 1 cluster. ...

... On exposures affected by it, the warning InvalidObtValue is generated during the processing. This will be fixed with a software update, available in future SAS versions. ... If this problem occurs, you should process the affected pn exposures with SAS versions older than v6.0.0 (indeed, it is enough to run the SAS v5.4.1 epframes , and then, for instance, re-use the output files in a subsequent epchain run, specifying the parameter runepframes=N ).
