Fig 5. A comparison of predicted against observed measles Lyapunov exponents for two biennial attractors.

Fig 5

A) Local Lyapunov exponents (LLEs) across the 1920–1935 biennial attractor predicted for mean birth rates. The filled blue circles indicate positive values with red indicating negative values. The size of the circle corresponds to the absolute value of the exponent. B) The observed LLEs across the 1920–1935 range using the true birth rates. C) Predicted LLE for the 1950–1965 biennial attractor using mean birth rates. D) Observed LLEs for the 1950–1965 data using the true birth rates.
