Auxiliary function used to define the occurrence threshold used to define node presences
Usage
find_threshold(
x,
threshold.steps = c(0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9)
)
Arguments
- x
A matri containing the continuous probabilities of occurrences of
nodes accross the sites
- threshold.steps
A numeric vector defining the threshold values that will
be compared in the procedure
Value
A list object containing the following information:
\itemize{
\item Maximum_site_probability: a vector containing the maximum probability
of occurrence of nodes for ech site
\item Removed_sites
\item Correlation_between_steps
\item Select_threshold: a scalar indicating the selected threshold
}
