Create a lower-is-better scoring rule

Creates a scoring rule object for indicators where lower values indicate better soil quality. The rule will normalize values using inverted min-max normalization: (max - x) / (max - min).

Usage

lower_better(min_value = NULL, max_value = NULL)

Arguments

min_value

Optional minimum value for normalization. If NULL, the minimum will be calculated from the data.

max_value

Optional maximum value for normalization. If NULL, the maximum will be calculated from the data.

Value

A scoring_rule object of class c("scoring_rule", "lower_better")

Examples

# Create a rule for bulk density (lower is better)
bd_rule <- lower_better()

# With custom min/max values
bd_rule <- lower_better(min_value = 1.0, max_value = 1.8)
