WebQuality planning should occur as part of the development of project deliverable specifications and work planning. As indicated in Table 7-1 above, quality planning for GIS projects may include several important aspects, some of which overlap with those identified for information technology projects, and some of which are unique to GIS. WebIt is precisely in such cases that the permutation test produces more reliable results than a "canned" test based on referring a "Z score" to a Normal distribution. For testing model residuals, in each iteration you would usually permute the residuals, refit the model, and compute Moran's I from those new residuals. References
