question: converts a vector of numbers into an array of double . this function does not necessarily belong here , but is commonly required in order to apply the statistical functions conveniently , since they only deal with arrays of double . note that a number of the common superclass of all the object versions of the primitives , such as integer , double etc. . concode_field_sep PlaceHolder placeHolder concode_field_sep double max concode_elem_sep void analyse concode_elem_sep void analyse concode_elem_sep String rmsString concode_elem_sep void main concode_elem_sep double stderr concode_elem_sep double correlation2 concode_elem_sep double min concode_elem_sep double correlation concode_elem_sep double sqr concode_elem_sep double variance concode_elem_sep double mean concode_elem_sep double mean concode_elem_sep double sdev concode_elem_sep String analysisString concode_elem_sep double variance2 concode_elem_sep double covar
