Self-Similarity of the Logistic Function




Logistic, f 3:


Below are images of f 3 (left) and f (centre) for various values of the parameter a (a value for f 3 / a value for f ), and the time series for f at this parameter value (right). The image of f 3 is a portion from the entire graph of f 3 (as seen above) - in particular, the piece in the middle near the diagonal line - inverted and enlarged to we can compare it to the graph of f. (See also Figures 11.30,11.31 pp625,26 in text.)

Period 1 (a = 3.84 / 2.8)

Period 2 (a = 3.848 / 3.3)

Period 4 (a = 3.849 / 3.5)

Ergodic (a = 3.857 / 4.0)
