How do I plot data with a regression line on top of the scatter plot?

Solarmew — Mon, 04 Sep 2017 18:17:57 GMT

I have some data:

x = 1 0 2 0 3 1 0 1 2 0;
y = 16 9 17 12 22 13 8 15 19 11;

I'd like to generate an estimated regression function and plot the line on top of the data scatter plot.

I tried searching for a tutorial or some kind of example, but couldn't find any (that I understood and that worked when i tried plugging them in).

Hi,

Try proc sgplot.

Not sure if this is what you are after?

data have;
input x y;
datalines;
1 16 
0 9 
2 17 
0 12 
3 22 
1 13 
0 8 
1 15 
2 19 
0 11
;

ods select FitPlot;
proc reg data=have;
   model y = x;
run;quit;

And the SGPLOT - which gives you more control over the colours and graph attributes:

title 'My demo plot';
proc sgplot data=have;
scatter x=x y=y ;
reg x=x y=y / lineattrs=(color=CXf03b20);
run;
