RegisterMutivariate test for profile similarity [Dissolution / BCS / IVIVC]
Dear all,
in
the authors describe a test for the comparison of drug dissolution profiles which is - in the eyes of the authors - more powerful then others, like similarity factor f2, IUT test ...
This test uses the variance-covariance matrix and therefore needs the individual values of %dissolved. But in the examples given in the paper I found only means and SD for the measurement time points.
Thus I couldn't recalculate the authors values for their new delta statistic if I understand their formulas (many matrices in there
) some days.
My question: Has anybody examples of the application of this test with all necessary data? Is there any code (SAS, R or whatever) out there?
