The line of best fit is R(t) =A + B.t where
A = 0.059308807
B = -0.001598269
The chosen Barnett curve is y(t) =a.(e^(-bt+d) - e^(-ct)) where
a = 0.273279
b = 0.1874
c = 0.571
d = 0.01
and therefore, for this mathematical model,
mean age = 7.11
modal age = 3
theoretical age when maximum citation rate occurs, T = 2.88
