lthough spatial incidences data
in Thailand were not used, signif icant
relationship is found conforming to the results
of Zhou (7), as well as some climate variables
such as; RH and Rainfall are no lagged
period (Table 1). However, these data are
surveillance and spatial analysis was not
used.
Nonlinear mixed regression analysis
Variables were selected and tested
with time lag period climate variable
associated with malaria incidence. The next
step is regression analysis by stepwise
method. The model was tested in three
assumptions as following.
- Model No EV assuming the
environment factors having no affect to the
number of patients; (g(x) = 0).
- Model 1 assuming the environmental
factors having an inf luence on the number
of patients given g (x) ≠ 0 and assuming
the interaction between all climate variables
= 0 due to no interaction with the environment.
- Model 2 assuming the environmental
factors having an inf luence on the number
of patients given g (x) ≠ 0 and assuming
