mini
is a list of 6 components: x, xtest, yB, yBtest, yC and yCtest. "x" is a numeric matrix with 55 samples (rows) across 4999 genes (columns). "xtest" is a numeric matrix with 65 samples (rows) across the same 4999 genes (columns). They are subsets of the original brainCancer
data. One gene is left out. "yC" and "yCtest" are continuous outcomes equal to the expression values of the left out gene in the training and test set respectively. "yB" and "yBtest" are binary outcomes dichotomized at the median based on "yC" and "yCtest".
