## Plotting the fit
* Size of points are frequencies at that X, Y combination.
* For the red lie the child is outcome.
* For the red line the child is outcome.
* For the blue, the parent is the outcome (accounting for the fact that the response is plotted on the horizontal axis).
* Black line assumes $Cor(Y, X) = 1$ (slope is $Sd(Y)/Sd(x)$).
* Big black dot is $(\bar X, \bar Y)$.
