Three residual plots for Regression model 2 were generated: EXPEND vs.
residuals, TAKESAT vs. residuals, and the predicted values of TOTALSAT
vs. residuals. In the third plot, a linear equation has been fitted to
the data.

HETEROSKEDASTICITY
I am attaching three different residual plots. I am trying to determine whether heteroskedasticity is present. I don't believe I see any pattern indicative of heteroskedasticity (nonconstant variance). I know it can be difficult to detect - do you see any indication of this?
What is this?
