The line of best fit is R(t) =A + B.t where
A = 0.041705407
B = -0.000924193
The chosen Barnett curve is y(t) =a.(e^(-bt+d) - e^(-ct)) where
a = 0.0882741
b = 0.0752
c = 0.45
d = 0
and therefore, for this mathematical model,
mean age = 14.23
modal age = 5
theoretical age when maximum citation rate occurs, T = 4.77
