importanceCHSIZ-class: Class '"importanceCHSIZ"'

Description Objects from the Class Slots Extends Methods Author(s) References See Also Examples

This class holds the inclusion zone definition for the importance sampling variant/protocol of critical height sampling for standing trees.

Objects can be created by calls of the form new("importanceCHSIZ", ...). However, this is not recommended because the objects are fairly complex. Instead, one can use the object constructor "importanceCHSIZ" to create new objects.

This class is a subclass of “criticalHeightIZ” (see below). It adds no new slots to the definition of that class, so please refer to it for the slot definitions.
