[R] "Nash Equilibrium"

[Ravi Varadhan]

No, Spencer.  Nash-Sutcliff efficiency is due to John E. Nash. It is
unrelated to game theory.

The well-known Nash equilibrium in game theory is due to John Forbes Nash,
Jr.

Ravi.

Might something like "Nash-Sutcliffe Efficiency" be relevant?


I found this as follows:


library(sos)
(n <- ???nash)
# found 22 links in 11 packages


       Hope this helps.
