Dear All,
I need to calculate the optimal number of clusters for a classification based
on a large number of observations (tens of thousands).
Thibshirani et al. proposed the gap statistic for this purpose. I tried the
R-code developed by R. Jörnsten but R hangs with such amount of data ().
Is it available any other (optimised) code?
Any help would be appreciated, including suggestions about other alternatives
for the selection of an optimal number of cluster from large datasets.
Thanks,
