. Starting Step 2.5 - Generate a partial autocorrelation plot
.
let ydiff = sequential difference y
y1label Partial Autocorrelation
x1label Lag
x3label Partial Autocorrelation Plot of the Differenced Data
xtic offset 1 1
xlimits 0 50
spike on
set autocorrelation lag zero off
line blank solid solid solid blank blank
line color black black blue blue
