What is coverage in conformal prediction?5 answersCoverage in conformal prediction refers to the proportion of times that a prediction interval or set includes the true response value. Conformal prediction provides guarantees on coverage, ensuring that the constructed prediction intervals contain the true response with a specified probability. The coverage can vary based on the pattern of missing values in the data, with some missing patterns leading to under-coverage of the response. To address this issue, a novel framework called missing data augmentation has been proposed, which generates prediction intervals that are valid conditionally to the patterns of missing values. Conformal prediction's coverage guarantees are crucial for uncertainty quantification, especially in scenarios involving missing data and complex survey designs.
