Quantitative analysis for the wine dataset. a) top panel: The blue line represents the BW-statistic for the red and white wine dataset. The black line indicates the critical BW-value for rejecting the null hypothesis (i.e., no difference between the groups) at a Bonferonni adjusted alpha-level. The null hypothesis can be rejected when the blue line surpasses the black line. bottom panel: Intensity values of the frequency instances. Black lines indicate the red wine group. Red lines indicate the white wine group. b) close-up in region 7580-7690. c) close-up in the region 4180-4215. d) close-up in the region 6200-6235.
