I am not aware of anyone implementing that algorithm, but when I have time, I can have a try, super busy recently.

Hi,
I am trying to find any implementation of Statistical Data depth in SAS. Do you have any SAS code to compute it (I dont have IML).

The seminal paper for this is "MULTIVARIATE ANALYSIS BY DATA DEPTH: DESCRIPTIVE STATISTICS, GRAPHICS AND INFERENCE by BY REGINA Y. LIU, JESSE M. PARELIUS AND KESAR SINGH , The Annals of Statistics 1999, Vol. 27, No. 3, 783-858"

Nice finding! Great article -- it seems that SAS allocated the jobs equally to 4 cores.

How about you do a benchmark, like:
options nothreads ;
proc princomp data=_junky noprint;
var x:;
run;

options threads cpucount=2;
proc princomp data=_junky noprint;
var x:;
run;

options threads cpucount=3;
proc princomp data=_junky noprint;
var x:;
run;

options threads cpucount=4;
proc princomp data=_junky noprint;
var x:;
run;
