Isotone Optimization in R: Pool-Adjacent-Violators Algorithm (PAVA) and Active Set Methods
In this paper we give a general framework for isotone optimization. First we discuss a generalized version of the pool-adjacent-violators algorithm (PAVA) to minimize a separable convex function with simple chain constraints. Besides of general convex functions we extend existing PAVA implementation...
