  1. Measure of the Fisher linear discriminant measure ([23], p. 119) between post-onset symptomatic samples and the other samples on heatmaps (Figure 4), reconstruction error (RE) between the observed data and the MAP estimators, computational times (for an implementation in MATLAB 7.8.0 (R2009a) on a 3 GHz Intel(R) Core(TM)2 Duo processor), and corresponding number of iterations.
