Figure 9.7 Profiler to Match Target and Minimize Variance with Prediction Intervals
If Y is the modeled response, and you want a prediction interval for a new observation at xn, then:
s2|xn is the variance for the individual prediction at xn
s2Y|xn is the variance of the distribution of Y at xn
Because the variance of the individual prediction contains the variance of the distribution of Y, the effects of the changing variance for Y can be seen. Not only are the individual prediction intervals wider, but they can change shape with a change in the variance effects.
