Statistical analysis of DGGE profiles. (a) Classification success rate (cross-validated) versus number of PLS dimensions used. A local maximum of ~64% was obtained from a 4-factor model. Also shown are compact boxplots summarizing the results of PLS-DA permutation tests (using y-scrambling, 10,000 re-samples). (b) CVA scores plot derived from PLS scores (4 dimensions) of the DGGE data of faecal bacteria showing the relative positions of the UC, IBS, and control groups. (NB: fully-leave-sample-out cross-validated.)
