To Delete Points Lying Outside the Point Set
1. Click Points > Delete Outliers. The Delete Outliers dialog box opens.
2. Type a value for Sensitivity.
To differentiate between the points lying outside the point set and the legitimate data points, specify a value from 0to 1. A lower sensitivity value means that points are selected farther from the point set, while a higher value means points are selected closer to the point set.
3. If required, click Preview. The points that lie outside the point set are highlighted.
4. Click OK.
