Displaying Possible Dependence Characteristics
Upon running the scanner under the Dependence tab, the Possible Dependence Characteristics area displays the possible dependency that the measurement fields may have upon the values from the property fields.
The columns that appear in this area are:
- Feature Id—Name of the field pairs, which are considered for dependence analysis. The property name and the measurement field names that are paired up are separated by a colon.
- Description—Prediction by the KS6800A software of whether or not the measurement field is dependent on the property field. The description statement is:
- The field <field_name1> appears to be depend on the value of <field_name2>.
- Score—A value that the KS6800A software derives at, using the ANOVA (ANalysis Of VAriance) test, where a series of unidirectional tests are performed to determine if the means of each possible independent value are identical, thereby, indicating dependency level of the measurement field values on the property field values.
You may view either 5, 10 (default), 25 or 50 rows per page. Use the navigation buttons to view the rows displayed on another page.
To view a graphical analysis of whether a field meets the conditions for dependency or not:
- Click the row you wish to analyze.
- Hover the cursor on the charts displays the corresponding values.
- Click the legend info to hide / view part of the plotted chart.
- Perform the following in-chart functions.

Let us understand the chart type that is plotted in a dependency analysis within the KS6800A environment:
- Breakdown by <Independent_Field_Name>—This chart shows a notched box and whisker plot, where the notch displays the Confidence Interval around the median. If the notches from two boxes do not overlap, there is strong evidence (or, 95% confidence) that their medians differ, which indicates that the boxes were drawn from different distributions.
- After analyzing the chart, you may choose one of the following options:
- For the query Should <Measurement_field_name> depend on <Property_field_name>?, click the Confirm dependence button so that the KS6800A software considers the fields for any dependence outliers.
- For the option Ignore dependence between <Measurement_field_name> and <Property_field_name> when considering outliers, click the Ignore dependence button so that the KS6800A software ignores the fields from consideration for any dependency outliers, even if there may be dependency errors among the selected pair of fields.
After selecting an option, the display returns to the previous page and the entry for the corresponding appears under Confirmed Dependence Characteristics. For more details, see Displaying Confirmed Dependence Characteristics.
