Regression i Maple - finding the best possible curve

Given some data points plotted in a graph by:

plot(<<a>|<b>>,style=point);

How do I do regression through the points? That is finding the best possible curve, straight line etc.

You could look at the help-pages for the CurveFitting package, or those of Statistics,Regression. (Note that the latter of those should appear by entering regression in the Maple 16 Help browser's search box.)

a:=<1,2,3,4,5>:
b:=<2,5,10,17,26>:

P1:=plot(<a|b>,style=point,color=red):

C1:=Statistics:-Fit(s+t*x,a,b,x);

C2:=Statistics:-Fit(s+t*x+u*x^2,a,b,x);

plots:-display( 
            P1,
            plot(C1, x=min(a)..max(a), color=green),
            plot(C2, x=min(a)..max(a), color=blue)
              );
