returns the standard deviation as a double primitive . if the underlying standard deviation is null , this method will return double.nan . concode_field_sep Number mean concode_elem_sep long serialVersionUID concode_elem_sep Number standardDeviation concode_field_sep Number getStandardDeviation concode_elem_sep double getMeanValue concode_elem_sep boolean equals concode_elem_sep Number getMean concode_elem_sep String toString
double function ( ) { double loc0 = Double . NaN ; if ( this . standardDeviation != null ) { loc0 = this . standardDeviation . doubleValue ( ) ; } return loc0 ; }
