Phytophthora ensemble risk
phytorisk_ensemble.RdCalculates Phytophthora cinnamomi's ensemble risk from mechanisms
Usage
phytorisk_ensemble(
mec_soilwater,
mec_rootcontact,
mec_surfacewater,
mec_zoospread = NULL,
weights = "equal"
)Arguments
- mec_soilwater
the result of mec_soilwater
- mec_rootcontact
the result of mec_rootcontact
- mec_surfacewater
the result of mec_surfacewater
- mec_zoospread
optional module. The result of mec_zoospread
- weights
weights of the ensemble model. The default uses the same weights for each model. The argument accepts a numeric vector with the corresponding weights. See Details
Details
This function calculates the ensemble risk as the weighted sum of the individual risk models as follows:
\(Risk = w_1 \cdot Mec_{soilwater} + w_2 \cdot Mec_{rootcontact} + w_3 \cdot Mec_{mec_surfacewater} + w_4 \cdot Mec_{zoospread}\).
Being \(w_i = 0.25\) when mec_zoospread is not null, and \(w_i = \frac{1}{3}\) when mec_zoospread is null. Additionally, the user can specify a numeric vector of length 3 or 4 specifying the desired weights based on expert criteria.
