The line of best fit is R(t) =A + B.t where
A = 0.044515019
B = -0.001022268
The chosen Barnett curve is y(t) =a.(e^(-bt+d) - e^(-ct)) where
a = 0.108484
b = 0.0864
c = 0.4
d = 0.001
and therefore, for this mathematical model,
mean age = 13.32
modal age = 4
theoretical age when maximum citation rate occurs, T = 4.88
