MATLAB: How to force the intercept of a regression line to zero

Question

Hi; How to set the intercept of a regression line,, resulted from fitlm, to zero?

 clc
X = 1:10
y = [1, 2, 2.9, 4, 5.1, 6, 7, 7.8, 8.6, 9.5]
dlm = fitlm(X,y)

Thank you, in advance, for your help.

Answer 1

There are 2 main ways you can do this:

dlm = fitlm(X,y,'Intercept',false);

or using Wilkinson notation:

dlm = fitlm(X,y,'y~x1-1');

I would highly suggest learning the Wilkinson notation, as this allows you to fit models and specify the form of the equation you would like to fit.
