Subject: Within and Between matrix
Hi the list...
I am working on cluster analysis, more precisely on Calinski and
Harabasz criterion
( C(g)=Trace(between)/Trace(Within)*(n-g)/(g-1)) )
Is there a package for calculating within and between matrix?
Morever, when we are using matrix with missing value, how do they
handle it? On a more theorical point of view, how shall we do?
Imputation will probably underestimate it, isn't it ?
Christophe
