    r7418 r7420  
    3030   * mfbase/MFEventSelector.cc:
    3131     - also reset fSelRatio if totalnumber of events from file.
     32
     33   * mranforest/MHRanForestGini.[h,cc]:
     34     - added a TPaveText containing text information to output
     35
     36   * mranforest/MRanForest.[h,cc]:
     37     - replaced type of fClassify by Bool_t
     38     - improved handling of allocated memory (still to be checked
     39       further)
     40
     41   * mranforest/MRanForestCalc.[h,cc]:
     42     - added another training type
     43     - added some comments

     47
     48   * mjtrain/MJTrainDisp.cc, mjtrain/MJTrainEnegry.cc:
     49     - renamed TrainSingleRF to TrainRegression
     50
     51   * mjtrain/MJTrainDisp.cc:
     52     - replaced training variable (hypot(dist,dca)) by dist
     53
     54   * mjtrain/MJTrainRanForest.cc:
     55     - added some comment
     56
