WebApr 24, 2014 · Basically, correct if I am wrong, given n samples classified in several classes, Fisher's LDA tries to find an axis that projecting thereon should maximize the value J (w), which is the ratio of total sample variance to the sum of variances within separate classes. I think this can be used to find the most useful features for each class. WebThe values in scores are the negative logs of the p -values. If a p -value is smaller than eps (0), then the corresponding score value is Inf. Before creating a bar plot, determine whether scores includes Inf values. idxInf … orb of primal flame wow
