ANOVA effect size for the log-information, I = log10(n/p), and correlation, ρ (defined as in (3)), from a linear regression using log relative imputation error, log10(ℰR(ℐ)), as the response. In addition to I and ρ, dependent variables in the regression included type of RF procedure used. ANOVA effect sizes are the estimated coefficients of the standardized variable (standardized to have mean zero and variance 1). This demonstrates the importance of correlation in assessing imputation performance.
