I Use the Line

Lyric copyright by Dennis Pearl
may sing to tune of "I Walk the Line" (Johnny Cash)

I keep a close watch on this scatterplot of mine
I keep applying regression all the time
I keep R-Squared to be the tie that binds
Because that's fine,
I use the line

I find it very, very easy to do least squares
I find another optimum and nobody cares
Yes, I'll admit I'm a fool for rms errors
Because that's fine,
I use the line

As sure as night is dark and day is light
I keep regression on my mind both day and night
And Gauss-Markov proves that it is right
Because that's fine,
I use the line

I check for patterns in my residual plots
I check again for any wayward dots
I could try splines, but I can't find the knots
Because that's fine,
I use the line

I keep close to y when I have this x of mine
I keep applying regression all the time
I keep R-Squared to be the tie that binds
Because that's fine,
I use the line
