...any bottom-up methods. Tools that graphically integrate mutual clusters into bottom-up methods are also included in the library. Lastly, an implementation of Michael Eisen's bottom-up clustering algorithm is also in the library. A paper, soon to appear in Biostatistics, describes this work: Chipman, H., and Tibshirani, R.

This worked for me with your example: source("dumpdata.R") storage.mode(x.hc$merge) <- "integer" plot(x.hc) (R-1.4.1 compiled from source on WinNT4.)

...s) MS SQL server, so licensing should not be an issue.... Although I have figured out this is possible (and implemented a similar system many years ago in a long forgotten language), I haven't built an MS OLAP cube yet -- so I haven't tested it. The following is summarized from Mary Chipman's and Andy Baron's, "Microsoft Access Guide to SQL Server," chapter 12, pages 644-654. SQL Server is capable of sending "pass through" queries for execution on another data base (using the foreign data base's syntax). That way "MDX is executed on the OLAP s...

.... I am having some trouble even encouraging NUT to build with snmp support, which doesn't seem to happen by default. I am curious if anyone has pointers, or if there is info summarized anywhere on this topic. All help is greatly appreciated. Relevant text is pasted below. Many thanks, Tim Chipman --------PASTE--------------- ./configure --with-drivers=snmp-ups runs, but I note in output: checking for Net-SNMP cflags... not found checking for Net-SNMP libs... not found note that this system has net-snmpd installed and snmp libs are visible under /usr/lib When I try to "make&quot...

...matrix (in the split function, x is a vector corresponding to one predictor). Without that, fitting a linear model in the terminal node would not be possible. Is this a correct assesment, or am I missing something? Has anyone tried to modify rpart to fit linear models in nodes? -- -- -- Hugh Chipman -- -- Associate Professor, Department of Statistics & Actuarial Science -- -- U. of Waterloo, 200 University Ave. W, Waterloo, Ontario, N2L 3G1 -- -- (519) 888-4567 ext. 6190 Fax: (519) 746-1875 -- -- www.stats.uwaterloo....
