Hi, I have a modeling equation and a set of data points, and I want to compute the accuracy of my equation relative to the data points. Is there anyway to compute the R squared value of my equation relative to these data points? All of the commands I can find in Statistics are used to fit an equation to the data points, which I don't want to do, I just want to have a qualitative measurement of how accurate my equation is.
