In this paper we compare theE(3) cubic spline with the not-a-knot cubic spline and we will show that theE(3) cubic spline is more accurate than the second one, and also, it has superconvergence properties which the not-a-knot cubic spline does not have. These superconvergence properties ...
In this paper, the main idea of the not-a-knot cubic spline of De Boor [8] will be extended to all the interior points (knots) of the spline interval to obtain a piecewise interpolatory cubic polynomial. Instead of the original and conventional not-a-knot cubic spline, to construct this...

Depending on the specific spline tool used, you can often set the boundary conditions. Spline, for example, allows you to set the end point slopes. However, by default, spline uses what are called the not-a-knot end conditions. That is, spline creates an everywhere ...
"...Bezier curves are a specific type of B-spline with a nonperiodic knot sequence..." "...any Bezier spline can be derived as a B-spline with a nonperiodic knot sequence..." Once we have created our fancy curves, there is one thing to keep in mind: Fusion 360...
Instead of the original and conventional not-a-knot cubic spline, to construct this piecewise polynomial we do not need to solve a tridiagonal system of linear equations, and this provides a shortcut which helps us save the time of doing more computations. The order of convergence of this ...
The linearity assumption of the age covariate was tested by comparing a model with a restricted 3-knot cubic spline basis for age to a model with a linear assumption for age, using a Wald test. For FN, bacterial BSI, and Gram-negative BSI, the linearity assumption did not hold, and age...
