question: protected double distance ( int i , int k , int [ ] designations ) { return Math . sqrt ( Math . max ( selfK [ i ] - 2.0 / ownes [ k ] * evalSumK ( i , k , designations ) + meanSqrdNorms [ k ] * normConsts [ k ] , 0 ) ) ; }
target:  Computes the distance between one data point and a specified mean
