Spatial clustering of high (Hot spot), and low values (cold spot) for full immunization coverage. a) The observed +/− 3 Gi_bins in the map reflect statistical significance with 99% confidence level; the +/− 2 Gi_bins reflect a 95% confidence level; the +/− 1 Gi_bins reflect a 90% confidence level; and the clustering for features in bin 0 is not statistically significant. b & c) The z-score are used to measures the statistical significance given the number of features and their values. It helps to conclude whether to reject or not the null hypothesis, feature by feature
