[Solved] How to graph a partial correlation?

[yonder24]

Hi everyone,

I would like to be able to make a graph for a partial correlation. Of course, to do so, I'll need the new X and Y values. I used SPSS to calculate the partial correlation, but it doesn't seem to give me the new values.

Is it possible to calculate the new values and make a graph? If so, do you know how I might do that?



Thanks,
Scott

Sorry I wasn't clear

Sorry that I wasn't clear.

So, when you calculate a bivariate correlation, you have the values for variable 1 and the values for variable 2.

I then used SPSS to calculate a partial correlation using values for variable 3.

I now want to plot the partial correlation between variable 1 and variable 2. Is that possible?

Google "Michael Friendly" and "Sas graphics", you might turn up something. If all else fails, draw a venn diagram.

Re: How to graph a partial correlation?

I looked into it some more and found a way to plot a partial correlation on SPSS. Here's how, for those of you who would like to know.

Analyze -> Regression -> Linear Regression

Drag the independent variable of interest and the covariates into the Independent(s) space. Drag the dependent variable into the Dependent slot.

Then, click on "Plots..." and select "Produce all partial plots".

yes of course, i had forgot it. but bear in mind the variables in the x and y axes.
