I've got a problem with the R function spline.des.
I use the following arguments:
x_seq(0,1,length=200)
knot_quantile(x,(1:8)/9)
ord_3
k_sort(c(rep(range(x),ord,knot)))
derivs_rep(2,200)
When I do spline.des(k,x,ord,derivs)$design on Splus and on R, I don't
have the same results.
However, if I take an order ord=4 (ie a spline of degree 3), then, I
have the same re...
