It is interesting to see how all these quantititative parameters are useful for solving geological problems.

One surprising result was that the isometric log-ratio transformation did not provide any improvement with respect to the use of concentration data. The chapter ends with the description of multiple linear regression exemplified from UV absorbance data.
