Unformatted text preview: sig (scalar) significance of the rule cm (vector) length 4, vectorized confusion matrix ([a,c,b,d]: see below) truex (vector) binary vector indicating for each item in the group whether it was true or not truey (vector) binary vector indicating for each item in the contrast group whether it was true or not Descriptive rule significance is measured as the match between the given groups (inds1 = G1, inds2 = G2) and the rule being true or false. G1 G2 --------------- accuracy = (a+d) / (a+b+c+d) true | a | b | |-------------- mutuconf = a*a / ((a+b)(a+c)) false | c | d | --------------- accuracyI = a / (a+b+c) See also SOM_DRSIGNIF, SOM_DRMAKE.
