Hi
I fitted the data using the fminsearch. I am able to find the slope and intercept of the fitted equation but, how to find the Linear Regression (R2) value of the fitted equation?
code:
for i=1:3
y=[Y1{i,1}']
x=[X{i,1}']
A= fminsearch(@(par_fit) funccoats(par_fit,x,y),rand(1,2));
B(i,1)=A(:,1)
C(i,1)=A(:,2)
end
graph:
