k mean cluster vs proc rank

monster90 · Posted 07-30-2018 08:11 AM

Hi guys,

If I use proc rank with grouping function, what is the different between this method and the k mean clustering method?

Actually i do not see any other differentiation only that with using proc rank (with group) the procedure wants to divide the groups in equal part...

Thanks your answer,

Steve

I won't comment on k-means clustering method, but ...

proc rank cares about order, but not distance, however distance is defined. And of course this is associated with only permitting equal-size groups.
proc rank doesn't do multi-dimensional "clustering", however defined. I presume the clustering method does do multi-dimensional.

--------------------------
The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set

Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for
Allow PROC SORT to output multiple datasets

PROC RANK computes ranks on individual variables.

K-mean clusters finds groupings of observations in your data set using multiple variables.

These don't do the same things.
