STATSF_SUM_X_Y(3)	   Library Functions Manual	     STATSF_SUM_X_Y(3)

LIBRARY
       #include	<statsf.h>
       -lbasic-stats -lxtend

SYNOPSIS
       STATSF_SUM_X_Y(ptr)

ARGUMENTS
       ptr	       Pointer to a statsf_t structure

DESCRIPTION
       Accessor	 macro	for sum_x_y.  Use this macro to	reference sum_x_y in a
       statsf_t	structure from functions that are not members  of  the	class.
       This allows separation of implementation	from interface.	 While the im-
       plementation  of	 the  statsf_t structure may change, effort is made to
       preserve	the API	of functions and macros	used to	access it.

EXAMPLES
       statsf_t	       statsf;
       double	       sum_x_y;

       sum_x_y = STATSF_SUM_X_Y(&statsf);

SEE ALSO
       See statsf.h for	a full list of macros.
