Advanced Statistics

Global Conditions

Use the Advanced Statistics option to generate statistics and graphs. The graphs can be displayed in Vulcan as well as generated directly in Microsoft Excel.


Instructions

On the Analyse menu, point to Statistics, and then click Advanced Statistics to display the following panel.

Global Conditions

Global Conditions template

Enter, or select from the drop-down list, the name of the template to save to. The current state of the Data Elements section (that is, all data types, attributes and conditions) can be saved to a template. Select the Save As button to save the template. If the chosen template already exists, then you will need to confirm whether or not you want to overwrite it.

Condition Title

Enter the condition title (a maximum size of 40 alphanumeric characters), for example 'Grade above 0.4'. The condition title will appear on the statistics/graphs below the plot title.

Condition expression

Enter the expression (a maximum size of 132 alphanumeric characters), for example $w gt 0.4. See Appendix B of the Vulcan Core documentation for a list of available operators/conditions.

Tip:  Use $w for the W tag variable and $s for the character tag variable to set the condition on multiple datasets. When a drillhole database is used to run advanced statistics it is not possible to limit the data by a condition in a field located in a different table. For example: Run a general stats in ASSAY:AU limit by GEOL:LITH field.

Bound Tri

Select this check box to use a triangulation to limit the dataset. Only those samples that fall in the specified triangulation will be used in the analysis.

Tri Settings

Click to edit the settings for the triangulation. The following panel displays.

Use this panel to select the triangulation that will be used to insert the points.

Enter the triangulation name or select it from the drop-down list. The drop-down list contains all triangulation files found in the current working directory. Click Browse to select a triangulation file from a different location.

Use the Pick From Screen button to select a triangulation directly from the screen.
