How do you calculater correlation coefficients for data?

[Z-Man]

I would like to calculate the correlation coefficient for data which has a linear correlation. I can calculate the linear fit, but how do you calculate the correlation coefficient from this data. Any help would be greatly appreciated.

Hi,
AutoCorrelation and CrossCorrelation VIs callculate correlation of the input signals. They are located under Signal Processing>>Time Domain palette.

Hi Greg,
Your answer for Cross Corellation is helpful to me. I downloaded the vi and try to run the vi you attached with your online answer. Looks like I am missing "Greg's Mean G01.vi". Could you please e-mail me that vi so I can run whole program to see how CC works.

Thanks,

If you're just looking for the correlation coefficient (r^2 or r) of a linear regression, you can use the method described HERE earlier.
