Hello Simon,
thanks for your response!
I incorporated the intercept, i.e. coef(my_gam)[1] into the spline. That
is, my B-spline coefficients are the intercept for the first one, and
for all others I added the intercept to them (see the code below if I'm
not clear)
Now I *almost* reproduce t
mgcv:gam automatically imposes sum-to-zero constraints on the smooths in
a model (even if there is only one smooth). This is to avoid lack of
identifiability with the intercept. The constraint removes one
coefficient and shifts the curve...
best,
Simon
