Hello Everyone,
I was wondering if there is a statistical method to compare two linear equations. I have one "nominal" equation y1=a1*x+b1 and one equation found using linear regression on a data set, y2=a2*x+b2.
I know I can just "look" and compare the slope and intercept values but it would be nice to have a numerical gauge.
I was thinking, I can determine the R^2 value between the data points and y2 but is there anyway I can find the R^2 value between the data points and the "nominal" equation?
Please excuse my *ahem, non-existent* stats...
Thanks in advance!
