 Let x be the response for ln-AUC for a subject following the Test
    formulation, and let y be the response be the response for
    ln-AUC for a subject following the Reference formulation.

Consider the Tmax data in Example 1 (recall this is in data set
  twobytwo of exam3.1.sas).
Calculate the individual differences for this Tmax data and
  construct NPPs and histograms.
Decide whether this data looks normally distributed.

              Week 2 Homework Q3
Consider data set week2 available at
  http://www82.homepage.villanova.edu/scott.patterson/.
Calculate the individual differences for ln −AUC and for
  ln −Cmax and construct paired agreement plots. Descriptively
  assess whether period or sequence effects are present.
Perform average bioequivalence assessment for AUC and Cmax
   and review MIXED output.
Check for outliers and perform sensitivity analysis if needed.
