Weighting Options

Weighting can be applied to account for the sampling bias introduced by orientation data collection along Traverses.

The following views are affected by weighting:

• Stereonet 2D
• Stereonet 3D
• Rosette
• Joint Frequency
• Kinematic Sensitivity
• Histogram
• Cumulative
• Scatter

To apply or remove the Weighting:

1. Select the Weighting > Apply Weighting toggle button in the appropriate contextual ribbon (i.e., Stereonet 2D, Stereonet 3D, Rosette, Chart).

To edit the weighting options:

1. Select Weighting > Weighting Options from the Analysis ribbon.
2. Enter the Minimum Bias Angle.
3. Click OK.

Minimum Bias Angle

The Minimum Bias Angle is actually a limit used by the Terzaghi correction, to prevent the weighting factor from becoming excessively large. It is set to a default value of 15 degrees. The maximum possible weighting factor corresponds to the Minimum Bias Angle. Any planes which intersect a Traverse orientation at an angle less than the Minimum Bias Angle will be limited to the maximum weighting factor. The Minimum Bias Angle must be greater than 0 and less than 90 degrees.
