How to ...
2. The Select Analysis Type to Run dialog should now appear. Select the Correlation Analysis button from the
list of Analysis Functions. Click the ADD button to create a new saved Correlation Analysis or select a saved
analysis from the list.
3. If creating a new analysis to save, the first step is to give a custom name and description to the new
analysis function. Click the NEXT> button to continue.
4. The Select Analysis Input Datasets dialog should now appear. This dialog allows you to select the data that
will be used in your correlation analysis. Two options for adding input datasets are provided:

Add Dataset - This option allows you to select any dataset from the system using the
standard Select Data Filter.

Add All Datasets from Map - This option adds any datasets/layers that you have open
in the current map into the list of input datasets for analysis.
Once you have made your selections for inputs to select attributes from, click the NEXT> button.
4. The Select Correlation Attributes dialog will now appear. This dialog allows you to select the attributes that
are available based on the Input Dataset that you selected and that you would like used in your correlation
analysis. Add the attributes from the Available Items list into the Selected Items list that you want to use in
the correlation. Click the FINISH button once you have made your selections. Make sure to pick at least two
different attributes.
5. Your analysis function has now been created and saved automatically. To run the saved analysis function
you just built, make sure you select the function in the list of saved analysis' and then select either the
Single Field button or the Multiple Fields button to run your analysis. A dataset filter will now appear that will
allow you to select data from a single field or multiple fields depending on the option you selected. Click
NEXT> once you have selected your dataset filter, then review the datasets that have been found for use in
your analysis and then click FINISH run to the analysis.
6. Once the analysis completes, you will return to the main window and an Analysis Document will be
displayed. You will see your correlation results in a matrix format, as well as tabs containing analysis charts
for the correlation data. You can now edit the analysis report/chart display options, such as logos, column
names, the attributes to display on the report, etc. by clicking your right mouse button on the report/chart
and selecting Edit Report/Chart Options or under the EDIT menu and OPTIONS.
7. Once you are satisfied with the Analysis Report/Chart(s) you can select to print the current document or
Save to HTML for a report or Save to Image for a chart. You can also save a workspace to see the currently
displayed results when you open the workspace again.
How to generate a cluster analysis dataset. (ADVANCED)
Follow these steps to generate a cluster analysis dataset:
1. Go to the Analysis Menu and select Analysis Wizard.
2. The Select Analysis Type to Run dialog should now appear. Select the Cluster Analysis button from the list
of Analysis Functions. Click the ADD button to create a new saved Cluster Analysis or select a saved
analysis from the list.
3. If creating a new analysis to save, the first step is to give a custom name and description to the new
analysis function. Click the NEXT> button to continue.
4. The Select Analysis Input Datasets dialog should now appear. This dialog allows you to select the data that
will be used in your cluster analysis. Two options for adding input datasets are provided:

Add Dataset - This option allows you to select any dataset from the system using the
standard Select Data Filter. .

Add All Datasets from Map - This option adds any datasets/layers that you have open
in the current map into the list of input datasets for analysis. This is very useful if you
are editing, viewing, etc datasets in a map and then decide that you want to use them
in a cluster analysis.
5. Once you have made your selections for inputs and set the gridding options for each input dataset, click the
NEXT> button.
6. The Select Cluster Attributes/Properties dialog will now appear. This dialog allows you to select the
attribute/properties that you want to generate a cluster analysis dataset for. The selected attributes can also
be set to be normalized, individually. Normalizing is very useful when you will be averaging data together
from the same operation but whose data ranges do not match, such as Soybean and Corn yields which are
not directly comparable in their normal form, but when normalized to a similar scale then they can be directly
compared. Two normalization methods are provided for you to select from. Once you have selected the
attributes/properties to cluster, click the NEXT> button.
7. The Cluster Settings dialog will now appear. Select the number of clusters that you would like to generate in
the result dataset. Click the FINISH button once the setting is made.
