Creates a scoring rule object for indicators with custom piecewise
linear scoring based on threshold-score pairs. Values are scored using
linear interpolation between the specified thresholds.
Usage
threshold_scoring(thresholds, scores)
Arguments
- thresholds
Numeric vector of threshold values (should be sorted
in ascending order)
- scores
Numeric vector of scores corresponding to each threshold.
Must have the same length as thresholds.
Value
A scoring_rule object of class c("scoring_rule",
"threshold_scoring")
Examples
# Create a rule for phosphorus with custom thresholds
p_rule <- threshold_scoring(
thresholds = c(0, 10, 20, 30),
scores = c(0, 0.5, 1.0, 1.0)
)
# Create a rule with non-linear scoring pattern
custom_rule <- threshold_scoring(
thresholds = c(0, 5, 15, 25, 40),
scores = c(0, 0.3, 0.8, 1.0, 0.9)
)
