Results of the test of synchrony for incidence time series and rainfall between 1989 and 1994.

Periodic Band

1.8–2.5 years

3–4 years

4–5 years

Incidence

Entropy = 0.7043

p-value < 0.0001

Entropy = 0.7407

p-value = 0.0004

Entropy = 0.7542

p-value = 0.0360

Rainfall

Entropy = 0.7276

p-value < 0.0001

Entropy = 0.7091

p-value = 0.0041

Entropy = 0.6327

p-value = 0.0669

The test was realized in three different periodic bands and based on normalized entropy, 0 for flat distribution and a 1 for unimodal distribution.
