Compound Extraction experiment of Dopico-Garc\' ia et al. (2007)

Description

An analytical experiment conducted by Dopico-Garc\' ia et al. (2007) to characterize the chemical composition of white grapes simultaneously determining the most important phenolic compounds and organic acids for the grapes. This example has been further studied in Phoa et al. (2009b) for one phenolic compound, kaempferol-3-Orutinoside + isorhamnetin-3-O glucoside, which is also what we studied. It is accepted for these data that fitting a main-effects model suggests that V3 (Factor C), V4 (Factor D), and interaction V1:V4 (A:D) are active effects.
