Fig. 4From: Fractal dimension analogous scale-invariant derivative of Hirsch’s index\(h_d\) values of controlled expectations of research field configuration v.s. the data. The fit function of green segment is \(y=0.8x+0.07\). Kendall’s rank correlation is 0.2 and \(\frac{Residual}{Data\ Variance}\) is 0.88Back to article page
