The line of best fit is R(t) =A + B.t where
A = 0.058009123
B = -0.001541748
The chosen Barnett curve is y(t) =a.(e^(-bt+d) - e^(-ct)) where
a = 0.22775
b = 0.1645
c = 0.571
d = 0.01
and therefore, for this mathematical model,
mean age = 7.84
modal age = 3
theoretical age when maximum citation rate occurs, T = 3.04
