Description: Tests whether a high or low level of a condition is enough
        to guarantee a high or low level of an outcome. Such a claim
        predicts that one corner of the condition-outcome scatter plot
        is empty of observations. The package estimates the boundary of
        that empty corner, its size as a share of the scope (the effect
        size), a permutation test against random pairing, and a
        threshold table giving the condition level that guarantees each
        outcome level, in actual units, percentages, percentiles or
        standard deviations. Each of the four directions (high or low
        condition, high or low outcome) is stated as a claim and mapped
        to its empty corner. Because a condition can rule out low
        outcomes while barely moving the average, results can be set
        beside ordinary least-squares and median regression slopes,
        showing whether the data hold an average effect, a sufficiency
        effect or both. Also provides plots, influential-case
        diagnostics, scope-sensitivity and resampling checks,
        random-data generation and power analysis for planning studies.
        Frontiers are estimated with the 'NCA' package.
