A recommended but underutilized method for modeling non-linear associations in regression models is spline functions. We explain spline functions in a non-mathematical way and illustrate the ...

The more I teach linear algebra, the more I think that perhaps it -- and not calculus -- ought to be the standard introductory math course for those majoring in “technical” fields (science ...

CheckIt bank for precalculus skills focused on algebraic functions. Originally written for first semester of a two-semester sequence through Calculus I with integrated precalculus. - allmanjm/pre-calc ...

Many data are suitably modeled by functions consisting of straight-line segments. These functions may be called piecewise-linear. Smooth functions that are related to the hyperbola and that have ...

In earlier work, we proposed to approximate the constrained linear quadratic regulator problem by representing input and state trajectories as linear combinations of basis functions. As a result, a ...
