^aFeatures are ranked based on order of selection by the stability selection approach
^bCoefficients of the logistic regression models. In the case of a multi-class problem (table B), coefficients of each of the binary regressions are shown. However, the direction and a magnitude of coefficients are hard to interpret due to a collinearity problem
^cUnivariate (point biserial) correlation coefficients showing the relationship of individual variable with different course groups
^dIDS, inventory of depressive symptomatology
^eNumber of DSM-IV diagnostic criteria met for a diagnosis of major depressive disorder (MDD)
^fRecency of dysthymia in months
