Measures spatial
autocorrelation for a series of distances and optionally creates a line graph
of those distances and their corresponding z-scores. Z-scores reflect the
intensity of spatial clustering, and statistically significant peak z-scores
indicate distances where spatial processes promoting clustering are most
pronounced. These peak distances are often appropriate values to use for tools
with a Distance Band or Distance Radius parameter.
يقيس الارتباط التلقائي المكاني لسلسلة من
المسافات وينشئ اختياريًا رسمًا بيانيًا خطيًا لتلك المسافات ودرجات z
المقابلة لها. تعكس درجات Z شدة
التجميع المكاني ، وتشير درجات الذروة ذات الدلالة الإحصائية إلى المسافات التي
تكون فيها العمليات المكانية التي تعزز التجميع أكثر وضوحًا. غالبًا ما تكون
مسافات الذروة هذه قيمًا مناسبة لاستخدامها في الأدوات ذات معلمة نطاق المسافة أو
معامل المسافة.

Input Field
The numeric field used in assessing spatial autocorrelation.
Number of Distance Bands
The number of times to increment the neighborhood size and analyze the
dataset for spatial autocorrelation. The starting point and size of the
increment are specified in the Beginning Distance and Distance Increment
parameters, respectively.
Beginning Distance (optional)
The distance at which to start the analysis of spatial autocorrelation and
the distance from which to increment. The value entered for this parameter
should be in the units of the Output Coordinate System environment setting.
Distance Increment (optional)
The distance to increase after each iteration. The distance used in the
analysis starts at the Beginning Distance and increases by the amount specified
in the Distance Increment. The value entered for this parameter should be in
the units of the Output Coordinate System environment setting.
Distance Method (optional)
Specifies how distances are calculated from each feature to neighboring
features.
·EUCLIDEAN—The straight-line distance between two points (as the crow
flies)
·MANHATTAN—The distance between two points measured along axes at right
angles (city block); calculated by summing the (absolute) difference between
the x- and y-coordinates
Row Standardization (optional)
Row standardization is recommended whenever the distribution of your
features is potentially biased due to sampling design or an imposed aggregation
scheme.
·Checked—Spatial weights will be standardized; each weight is divided by
its row sum (the sum of the weights of all neighboring features).
