Correlation and regression analysis were the major statistical tools used in this study for investing and selecting the statistical significance in the relationship between household’s activities and DHF patients. The results revealed that out of 167 variables, 15 variables that were correlated with the number of cases of DHF patients. Pearson’s correlation coefficient of 15 variables showed positive significantly correlation between household’s activities and DHF patients. It found that 6 out of 15 variables in this study showed significant correlated with DHF patients. of regression analysis
(E[ei] = 0, Var [ei] approximate 1, independent of ei and ej; Durbin-Watson = 1.819>1.5). Interval of VIF of all significant variables were 1.003-1.038 which less than 5. Results of residual analysis were then used for the verification of the applicability of assembled regression model. The existences of influential and outlier observations were checked but not found in the model (maximum of standard error was not more than 3) (Table 3).
