Differences between univariate and bivariate K functions to test for spatial segregation of each individual pattern, Mbulu district, Tanzania, 2003–2004.

The difference between the univariate and bivariate K functions for case households is denoted here by K₁–K*₁₂. On the other hand, K₂–K*₁₂ denotes the difference for control households, and r is the radius. Figure 5 A and B show the results based on Ag-ELISA incidence while C and D present results based on lingual examination incidence. Upper and lower 95% confidence limits for the K functions are indicated by dotted lines.
