Derive support in [0, 1] from a pair's ratings — score

Takes the whole vector of raters' native ratings, because the instrument decides where aggregation happens. IOC averages the +1/0/-1 ratings and reads support off the ladder; CVI dichotomizes each rater at the relevance cut and averages the indicators. Handing this function a pre-aggregated number would collapse that distinction.

Usage

score_strength(scoring_system, values)

## S7 method for class <curriculum::ScoringSystem>
score_strength(scoring_system, values)

## S7 method for class <curriculum::ContinuousScoringSystem>
score_strength(scoring_system, values)

Arguments

scoring_system: ScoringSystem object.
values: Numeric: Native ratings from one or more raters.

Value

Numeric scalar in [0, 1], NA if every rating is NA.
