If the median is not centered in the box, it shows sample skewness The "whiskers" are lines extending above and below each box. Whiskers are drawn from the ends of the interquartile ranges to the furthest observations within the whisker length (the adjacent values). Observations beyond the whisker length are marked as outliers. By default, an outlier is a value that is more than 1.5 times the interquartile range away from the top or bottom of the box, but this value can be adjusted with additional input arguments. Outliers are displayed with a red + sign.

Data with Gd enhancing lesions

Dendrogram or hierarchical cluster tree X=[T2LV_MAN,BPF_MAN] Standardized Euclidean distance. Each coordinate in the sum of squares is inverse weighted by the sample variance of that coordinate. Linkage with inner squared distance (minimum variance algorithm)
