Most crowding effects must be paired with an NCI term. The NCI term returns one or more values representing different indexes of neighborhood competitiveness. Each crowding effect term can be matched with a variety of different competitiveness indexes and each one below describes how it uses each NCI value it receives.
This can be paired with NCI terms returning either one or two values.
Parameter name | Description |
---|---|
NCI Crowding Effect Slope (C) | The "C" term in the crowding effect equation. |
NCI Crowding Effect Steepness (D) | The "D" term in the crowding effect equation. |
NCI Size Sensitivity to NCI (gamma) | The "gamma" term in the crowding effect equation. |
Crowding Effect is calculated as:
where:
The valid ranges on parameter values will depend on the choice of the NCI term.
This can be paired with NCI terms returning either one or two values.
