The line of best fit is R(t) =A + B.t where
A = 0.050691967
B = -0.001255384
The chosen Barnett curve is y(t) =a.(e^(-bt+d) - e^(-ct)) where
a = 0.156454
b = 0.1155
c = 0.4
d = 0.02
and therefore, for this mathematical model,
mean age = 10.91
modal age = 4
theoretical age when maximum citation rate occurs, T = 4.3
