Note: If these effects are used with NCI Mortality, the time period unit for parameters must match the value specified in the NCI Parameter Period (years) parameter.
Infection Effect "a" | The "a" parameter for the infection effect. |
Infection Effect "b" | The "b" parameter for the infection effect. |
Infection Effect is calculated as:
where:
Time infested comes from either the Density Dependent Infestation or Insect Infestation behaviors. Trees to which this behavior is applied must have one of these two behaviors also applied.
If a tree is not infested, there is no effect.
Infection Effect "a" | The "a" parameter for the infection effect. |
Infection Effect "b" | The "b" parameter for the infection effect. |
Infection Effect "X0" | The "X0" parameter for the infection effect. |
Infection Effect "Xb" | The "Xb" parameter for the infection effect. |
Infection Effect "Xp" | The "Xp" parameter for the infection effect. |
Infection Effect is a function of the size of the tree and the time since infested. It is calculated as:
where:
Time infested comes from either the Density Dependent Infestation or Insect Infestation behaviors. Trees to which this behavior is applied must have one of these two behaviors also applied.
If a tree is not infested, there is no effect.
