In them functions u0 are nothing more than piecewise-power (or piecewise-linear
for [alpha] = 3/2) functions of order [alpha].

In this work, we use the piecewise-linear
We use a piecewise-linear
(PWL) specification for our non-linear modeling of WTP over bag limits because this is the most general specification given the set-up of our SPCE.
Continuing from their 2014 Wilson Lines in Quantum Field Theory, which focuses on mathematical foundations and geometric properties, they develop ab initio calculation techniques applicable to generic piecewise-linear
Wilson lines, and present the practical tools for their implementation.

While other methods, as stochastic frontiers, need the specification of a functional form for the production function (such as the Cobb-Douglas form), DEA is a nonparametric technique that estimates a piecewise-linear
convex technology without this requirement, constructed such that no observation of the sample of data lies above it (refer to Figure 1).
Given a convex compact polytope K in [R.sup.p] (we are only concerned with the case K = O(P) here but the definition makes sense more generally), we define the piecewise-linear
toggle operation [[tau].sub.i] (1 [less than or equal to] i [less than or equal to] p) as the unique map from K to itself whose action on the 1-dimensional cross-sections of K in the ith coordinate direction is the linear map that switches the two endpoints of the cross-section.
