Table 4. Bivariate logistic regression of evacuation predictors on evacuation among all respondents and separately by presence or absence of traditional knowledge base.

Voluntary shelter evacuation
Independent variables All respondents
(N = 212)
Respondents without traditional knowledge base (N = 111) Respondents with traditional knowledge base (N = 101)
Indicators related to access, understanding, and interpretation of warning information
Severity of cyclone 2.42*** 1.289 5.82***
Landfall location of cyclone 2.61*** 1.71 4.07***
Landfall time of cyclone 2.35*** 1.43 4.07***
Evacuation order in the warning 1.51 1.28 1.57
Protective guidance in the warning 2.28*** 3.07*** 1.56
Clarity of the warning message 2.36*** 1.96* 2.57**
Type of channel 2.03** 1.5 2.77*
Estimate of damage due to cyclone given a particular severity 1.73** 1.012 3.73***
The number in the cells are exponentiated betas or odds ratios. An odds ratio of 1 (or not significantly different from 1) indicates no effect. An odds ratio larger (or smaller) than 1 indicates factor by which odds of evacuation are increased (or decreased) by one unit change in independent variable. *, **, *** represent the level of significance (alpha)
*** implies alpha ≤ 0.01
** implies alpha ≤ 0.05
* implies alpha ≤ 0.10
