TestStatistic that returns the ratio of profiled likelihoods.

By default the calculation is:

\[ \log{ \frac{ \lambda( \mu_{alt} , {conditional \: MLE \: for \: alt \: nuisance}) } { \lambda(\mu_{null} , {conditional \: MLE \: for \: null \: nuisance}) } } \]

where \( \lambda \) is the profile likeihood ratio, so the MLE for the null and alternate are subtracted off.

If SetSubtractMLE(false) then it calculates:
