statistics
The statistics module is used to analyze the statistical distribution of a field with nodal data. The data field can contain any number of data components. Statistical analyses can only be performed on scalar nodal data components. An error occurs if a statistical analysis is attempted on vector data. Output from the statistics module appears in the EVS Information Window. Output consists of calculated min and max values, the mean and standard deviation of the data set, the distribution of the data set, and the coordinate extents of the model.
The first port (the leftmost one) should contain a mesh with nodal data. If no nodal data is present, statistics will only report the extents and centroid of your mesh. Data sent to the statistics module for analysis will reflect any data transformation or manipulation performed in the upstream modules. Any mesh data sent to the port is used for calculating the X, Y and Z coordinate ranges. The mesh coordinates have no effect on the data distribution. Cell based data is not used.
Ports
| Direction | Name | Type | Description |
|---|---|---|---|
| Input | Input Field | Field | The field to use for statistic calculations. |
| Input | Z Scale | Number | The factor used to remove vertical scaling. |
| Output | Mean Level | Number | The calculated mean value. |
| Output | Median Level | Number | The calculated median value. |
| Output | Minimum Level | Number | The calculated minimum value. |
| Output | Maximum Level | Number | The calculated maximum value. |

| Output | Statistics | String | String representing the calculated statistics. |
Properties
| Property | Type | Description |
|---|---|---|
| Allow Run | Boolean | When the Allow Run toggle is set to on the module will run every time a setting is changed. |
| Execute | Button | This button will force the module to run even if the Allow Run toggle has been turned off. This allows the user to make a number of changes before updating. |
| Z Scale | Double | The Z exaggeration factor applied to the input field. |
Statistic Settings
| Property | Type | Description |
|---|---|---|
| Data Component | Choice | The Data Component on which the statistical analysis is to be performed. Options are populated from the input field. |
| Minimum Data Level | Double | The Minimum Data Level is used to set the lower limit on the data bins for statistical analysis. The default value is the minimum in the data component. If the statistical distribution should focus on only a portion of the data, this value can be changed to reflect only that desired range of data. |
| Maximum Data Level | Double | The Maximum Data Level is used to set the upper limit on the data bins for statistical analysis. The default value is the maximum in the data component. If the statistical distribution should focus on only a portion of the data, this value can be changed to reflect only that desired range of data. |
| Clamp Data | Boolean | The Clamp Data toggle will actually clamp the data to the Minimum and Maximum Data Level before processing it for statistics. |
| Number Of Bins | Integer | The Number of Bins is used to set the number of distribution bins to be used in the analysis. The default is 10 and the range is from 2 to 255. This value is generally changed to get unary or aesthetically pleasing bin values. |
| Details | Boolean | The Details toggle will display additional statistical information such as variance, deviation and quartile values. |
| Report Delimiter | String | The Report Delimiter string controls the spacing of the output window. The text of the output window will be broken up according to whatever is in the Delimiter box. The special delimiter tag ‘TAB’ allows the text to be tab delimited. |
| Coordinate Precision | Integer | The Coordinate Precision is the number of decimal points to use for coordinate values. |
| Format Data | Number Formatting | The Format Data control allows the user to set how data will be formatted for display. |
