Abstract
In this paper several examples of substantive error are discussed and ways in which these errors can be minimized to the point where they are trivial are described. Three main types of error are examined: the first concerns the effect of imposing a boundary on the system being investigated; the second concerns the estimation of spatial trends in data where the source of the trend is ambiguous, and the third concerns the effect of examining a relationship at different spatial scales. Each type of error is examined in the context of a specific type of analysis - that of estimating a density gradient - in which the local density of a spatial distribution at some point is related to the distance from the center of the distribution. -from Author
