The line of best fit is R(t) =A + B.t where
A = 0.04959541
B = -0.001215401
The chosen Barnett curve is y(t) =a.(e^(-bt+d) - e^(-ct)) where
a = 0.14397
b = 0.1094
c = 0.41
d = 0.017
and therefore, for this mathematical model,
mean age = 11.29
modal age = 4
theoretical age when maximum citation rate occurs, T = 4.34
