Abstract

A metabolite may be expressed on a group of variables in mass-spectrometry experiments. Evaluation on metabolite effects should consider this group. Group lasso regression can be used to evaluate these groups. It shrinks some regression coefficients to zero by intermediate penalty on OLS loss function. The data used were antioxidant activity and mass/charge ion from LC-MS output of Curcuma aeruginosa compositions of 3 areas in Java. The significance metabolite groups were 148,060, 202,179, 204,159, 228,123, 238,150, 246,133, 312,274, and 398,335.
