cluster analysis speed
in systat11 I am able to perform a hierarchical cluster analysis on a 125 by 1764 or so matrix in a reasonable clusetering the 125 rows, in reasonable time. my problem with systat is that the distance measure is supposed to be 1 - the pearson correlation coefficent, so distances should be between 0 and 2. yet i sometimes get distances greater than 2.
I want to compare the output from systat and statistixl using the same distance measure and linkage method
however, i am currently running statistixl on the same data set. i started more than 10 minutes ago. in the meantime i have run the same analysis in systat several times, each one finishing in less than 5 seconds.
i am not really concerned about the speed of statistxl.... but should it be quicker?
task manager tells me it aint responding... has it crashed excel or should i give it more time?
