Splines are a smooth and flexible way of fitting Non linear Models and learning the Non linear interactions from the data.In most of the methods in which we fit Non linear Models to data and learn Non linearities is by transforming the data or the variables by applying a Non linear ...

A stable system of recurrence relations for the coefficients of the spline in successive intervals is obtained by the methods of dynamic programming and they are shown to be identical with the usual relations of the spline approximation. Extension of this method to other types of splines is also...
qds<- quads3d(x1r[c(1,2,2,1)], x2r[c(1,1,2,2)], 0.5, alpha=0.4, color="gray", lit=FALSE) In the above graphic, the probability surface is represented in gray, and the Bayes decision boundary occurs where the plane f(x) = 0.5 (in light gray) intersects with the probabili...

The quantum diagonal properties are defined in the following fashion: h-diagonal property $$P(t)=p\bigl(t,t-h,\ldots,t-(d-1)h;h\bigr), $$ q-diagonal property $$P(t)=p\bigl(t,tq,\ldots,tq^{d-1};q\bigr). $$ We introduced the affine q-blossom in [27] to ...

In this software, group- based trajectory models can be fitted using the Latent Class regression option, which required the data to be in long form. We use R to calculate the B-spline basis, and the variables which make up this basis are added to the dataset and become the "predic- to...
