Having two parameters (θ k and θ l ) and performing WGS for only one parameter θ k , the F-Test confidence interval for the corresponding parameter is obtained since θ j is always adjusted. However, performing the MOC and limiting it to one parameter θ k , the confidence interval will always be smaller or equal to the correct F-Test confidence interval, since at SSE(θ MOC k ) = SSE max there is still the other parameter θ l to be adjusted. If there is no 1-20 correlation between θ k and θ l , both parameters can be varied independently of each other and the F-Test confidence interval of the Simplified Model Comparison and WGS are equal.
