The line of best fit is R(t) =A + B.t where
A = 0.052937253
B = -0.001337655
The chosen Barnett curve is y(t) =a.(e^(-bt+d) - e^(-ct)) where
a = 0.230639
b = 0.138
c = 0.338
d = 0.006
and therefore, for this mathematical model,
mean age = 10.13
modal age = 4
theoretical age when maximum citation rate occurs, T = 4.45
