Setting intercept to 0 in lmBF?
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.
