I have four variables pp, ph, ngl & yield. Suppose I want to find out Partial Correlation between NGL and yield after removing the linear effect of PP and PH. In Base SAS I can find out by using the following given code.

/*BASE SAS Code*/

proc corr;

var ngl yld;

partial pp ph;

run;

But In JMP, When i go to**Analyze** -> **Multivariate Methods** -> **Multivariate**. I selected all the variables and click OK. From Hotspot button I get Partial correlation of all the variables with respect to all other variables. See below the output of JMP.

Partial Corr

pp ph ngl yld

pp . 0.1315 0.2028 0.2825

ph 0.1315 . -0.0309 0.2686

ngl 0.2028 -0.0309 . 0.1920

yld 0.2825 0.2686 0.1920 .

partialed with respect to all other variables

**But I want to get partial correlation between ngl & yield after adjusting for pp & ph.**

Please reply.

Thanks.

Unless I misunderstand your question, from your output the partial correlation between ngl and yield after adjusting for pp and ph is 0.1920.
