# Setting intercept to 0 in lmBF?

Hi all,

I was wondering whether it is possible to force the intercept equal to 0 in lmBF. (Or, at least, I think that's what I need to do. Forgive my statistical shortcomings.)

What I have is a dataset in which I want to find the best fit from [linear, quadratic, cubic] fits, with the constraint that the intercept should be 0. I'd like to be able to say something like, "Assuming a polynomial of degree <= 3, and that the y-intercept is 0, the best fit for this data is f(x)."

Any help would be very much appreciated.

Best regards,

Rick

Hi Rick,

I'm not sure whether this can be accomplished (my personal probability is lower than 5%). If Richard does not reply, you could DM him; if you would you can post the answer here.
