Conditional Randomization

This approach is used to redistribute data values among spatial regions in the any method which uses randomization.  In each randomization, the value is held fixed for each spatial region, and the remaining values are randomly assigned new locations. Thus, the randomness is conditional—all regions get randomized frequencies but one. This process is repeated as each region is evaluated in turn.

Note that this approach may result in slightly different p-values when compared with previous version of SpaceStat.  Earlier versions did not use conditional randomization.
