Parameter Setup
Description
Given a c4c_concept concept definition, a list of parameter elements
is handed back. This information is required for simulations and subsequent
evaluations.
Usage
setup_parms(concept_def)
Arguments
concept_def |
Concept definition as a |
Details
The element risk as part of the output describe as 'normal' risk as
assumed for the silvicultural concept defined in concept_def. This can
be adjusted with the parameter avg_event_strength of the function
setup_risk_events, which has to be called in any case after the
parameter setup.
Value
A list with three elements. The first, dwell_time, is a vector
of dwell times for each subphase area, i.e. it indicates the average time a
unit area is dwelling in this subphase (assuming an exponential
distribution over time). The second element, risk, is a vector of
the same length and order. It represents, for each subphase area, the
average relative loss rate per year. It is derived from the cumulative
survival probabilities (survival_com) given in the data frame
growth_and_yield which is part of the concept definition
(concept_def). The third element, phase_indexes, is a tibble
which contains, for each stand development phase in concept_def, a
vector of indexes which can be used to easier access the phase wise
information in the different kinds of simulation outputs.
