Setting Criteria for Analyses
To specify when two threshold crossing events are considered as matching or not, a number of event matching criteria can be used. In the configuration file for the skill scores display it is possible to define default event matching criteria, which can be different for different locations and/or groups of locations. When the skill score display is opened, then the global criteria and the criteria settings for each location and group of locations are read from the configuration file. If for a given location/group individual criteria have been defined, then these are used and the location/group gets a green tickmark in the filterbox at the left hand side of the skill scores display. If for a given location/group no criteria have been defined, then the global criteria are used for that location/group.

To specifychange whatthe matching threshold crossings mean, a number of criteria can be used criteria of certain location(s) and/or group(s), first select the location(s) and/or group(s) in the filterbox at the left hand side of the display. Then click the \[Change Criteria\] button. When clicking the \[Change Criteria\] button the following display appears. |
The criteria in the display have the following meaning.
...
- Max time threshold being too early/late . These criteria define what the maximum difference between a forecasted threshold crossing and an observed threshold crossing are allowed to be in order to consider them as matching.
In the lower section of the display it is possible to choose between two options:
- Apply global: if this is selected, then all changes will be applied to the global criteria.
- Apply to selected: if this is selected, then all changes only apply to the groups and/or locations that have been selected in the skill scores display.
This way it is possible to change the criteria settings for individual locations/groups. If the global criteria are changed, then this has no effect on locations/groups which already have individual criteria settings. If a location/group has no individual criteria settings, then the global criteria are used for that location/group.
Matching Events
In the Matching Events tab different background colours are used to indicate in which sector of the Contingency Table events fall.
