Stat_t GetCorrelationFactor(Int_t axis1, Int_t axis2)
*-*-*-*-*-*-*-*Return correlation factor between axis1 and axis2*-*-*-*-*
*-*            ====================================================

Stat_t GetCovariance(Int_t axis1, Int_t axis2)
*-*-*-*-*-*-*-*Return covariance between axis1 and axis2*-*-*-*-*
*-*            ====================================================

void GetStats(Stat_t *stats)
 fill the array stats from the contents of this histogram
 The array stats must be correctly dimensionned in the calling program.
 stats[0] = sumw
 stats[1] = sumw2
 stats[2] = sumwx
 stats[3] = sumwx2
 stats[4] = sumwy
 stats[5] = sumwy2
 stats[6] = sumwxy

void PutStats(Stat_t *stats)
 Replace current statistics with the values in array stats

void Reset(Option_t *option)
*-*-*-*-*-*-*-*Reset this histogram: contents, errors, etc*-*-*-*-*-*-*-*
