question: @ Override public String toString ( ) { String s = "KDE(mean=[" ; double [ ] means = getMean ( ) ; for ( double mean : means ) { s += StringUtils . getShortForm ( mean ) + ", " ; } s = s . substring ( 0 , s . length ( ) - 2 ) + "]),std=" ; double avgstd = 0.0 ; for ( double std : getStandardDeviations ( ) ) { avgstd += std ; } s += StringUtils . getShortForm ( ( avgstd / means . length ) ) ; s += ") with " + points . length + " kernels " ; return s ; }
target:  Return a pretty print for the kernel density
