Results on LC-MS maps of urine samples. Left: Log-scaled Mahalanobis distances for the renal patient samples. The black line gives a cutoff for a significance level of 5%. Outlier are given red down-pointing triangles and their run numbers. Right: Projection of the LC-MS maps on their first two principal components. This plot shows that the data (scores) projected on the first two principal components and the variables (loadings) plotted as arrows.
