Voronoi diagram


Voronoi diagram is a partitioning of a plane into regions based on distance to points in a specific subset of the plane. That set of points (called seeds, sites, or generators) is specified beforehand, and for each seed there is a corresponding region consisting of all points closer to that seed than to any other. These regions are called Voronoi cells. Voronoi diagram is a technique of graph clustering (Polanco, 2013)

Analytical Framework for R&D analysis

Analytical Framework


R&D is a function of (GERD) and (Human resources) 

R&D = f(GERD, HR)

GERD = Goss domestic expenditure on R&D
Units for expenditure:
       National Currency
       2005 Dollars - Constant Prices and PPPs (PPP = Purchasing Power Parity)
       PPP Dollars - Current Prices
