Ok Thanks a lot

Joan,

He seems to be confused. He first asks how to draw the zone boundaries, and I guess he figured that out. But he wants to know how to compute the percentages of points falling in each zone. He will need to have code that checks every point to determine in which zone it lies. Then he will need code to count the number of points in each zone. It’s not an easy programing task; you need to check a lot of boundaries. It would be particularly difficult in SAS.

I do not know if this helps.

Bye for now,

Scott P.

To complete Consensus Error Grid to calculate percent in each area . I rescue to PROC GINSIDE. This PROC is awesome.

NOTE: unit is (mg/dL)

/*产生样本数据*/

  call streaminit(123);
    do i=1 to 500;

    end;

    /*--Add data all over--*/
    do i=1 to 100;
      x=550*ranuni(2);  y=550*ranuni(2); output;
    end;

    /*--Add data in the middle fan--*/
    do i=1 to 2000;
      x=40+360*ranuni(2);  
	  y=x+(x-50)*2*tan(pi/4 *ranuni(2) -pi/8);
	  y=ifn(y>550 or y<0, ., y);

Dear Ksharp,

Thank you so much for providing this code!

I am just new to SAS and am wondering how I insert my own two input arrays of model value and reference value.

Thank you so much in advance!

Kind regards,

Rody

You could replace my HAVE dataset with yours . a.k.a replace the following code .

/*产生样本数据*/
data have;
  pi=constant('PI');
  call streaminit(123);
    do i=1 to 500;
      x=40+30*ranuni(2);  y=40+40*ranuni(2); output;
    end;

    /*--Add data all over--*/
    do i=1 to 100;
      x=550*ranuni(2);  y=550*ranuni(2); output;
    end;

    /*--Add data in the middle fan--*/
    do i=1 to 2000;
      x=40+360*ranuni(2);  
	  y=x+(x-50)*2*tan(pi/4 *ranuni(2) -pi/8);
	  y=ifn(y>550 or y<0, ., y);
      output;
    end;
 keep x y;
run;

Or just type it by your hand. Like this :

data have;
input x y;
cards;
51.6 77.60
63.2 60.7
43.2 45.2
;
run;
