Block Model Statistics

This command is used to report data value statistics on each grid or overall statistics within the block model. The user is prompted to select one of  the reporting method, Report by Attribute/Quality or Report by Levels/Grids. The reports are generated using the Report Formatter. There is an option to select an inclusion perimeter to limit the report to an area. Otherwise the report will cover the whole block model.

The Report By Attribute/Quality reports statistics for all the samples of each attribute in the block model. Here's an example:

Name    Samples Min Value Max Value Avg Value Variance Std Dev
SIO2     143820      3.07     71.12     26.88    61.25    7.83
CAO      143820      4.03     53.31     34.78    47.13    6.86

The Report By Levels/Grids reports statistics for each attribute grid at each level in the block model. The attribute names in the report have the level sequence number as a suffix. The grid levels are numbered from 1 at the bottom and going up. Besides the statistics on the attribute values, the report also has statistics on the elevation and depth for each level. Here's an example portion of a report:
Name      Samples Min Value Max Value Average Value Std Dev Avg Top Z Avg Bot Z Avg Depth 
CAO[1]       1410     21.42     43.78         35.67 3.91     47.93     47.43    101.67 
CAO[2]       1410     20.96     43.71         35.67 3.99     49.92     48.93    100.17 
CAO[3]       1410     20.59     43.82         35.67 4.06     50.92     49.92     99.18 
CAO[4]       1410     20.37     43.88         35.68 4.14     51.92     50.92     98.18
