Associated Kernel Estimations (Ake)
Continuous and discrete (count or categorical) estimation of density, probability mass function (pmf) and regression functions are performed using associated kernels. The cross-validation technique and the local Bayesian procedure are also implemented for bandwidth selection.

Partial Linear Least-Squares Regression using Constrained Splines (ConSpline)
Given response y, continuous predictor x, and covariate matrix, the relationship between E(y) and x is estimated with a shape-constrained regression spline. Function outputs fits and various types of inference.
