It would be possible to conduct such modeling, if Wizards would release
quantifiable information about the unit sales volume of the core D&D
books, especially if that data could be combined with unit sales volume
data from the half-dozen major distributors to correlate with 3rd party
D20 product sales.  Unfortunately, neither set of data points is, or is
every likely to be, available.  :(
