Web##' The Taylor Diagram is a very useful model evaluation tool. ##' The diagram provides a way of showing how three complementary model ##' performance statistics vary simultaneously. These statistics are the ##' correlation coefficient R, the standard deviation (sigma) and the (centred) ##' root-mean-square error. Taylor diagrams are mathematical diagrams designed to graphically indicate which of several approximate representations (or models) of a system, process, or phenomenon is most realistic. This diagram, invented by Karl E. Taylor in 1994 (published in 2001 ) facilitates the comparative assessment of different models. It is used to quantify the degree of correspondence between the modeled and observed behavior in terms of three statistics: the Pearson correlation coefficient, the root …
