NMAoutlier: Detecting Outliers in Network Meta-Analysis

A set of functions providing several outlier (i.e., studies with extreme findings) and influential detection measures and methodologies in network meta-analysis: - Simple outlier and influential deletion measures provided: (a) Raw, (b) Standardized, (c) Studentized residuals; (d) Mahalanobis distance and (c) leverage. - Outlier and influential detection measures by considering study deletion (Shift the mean): (a) Raw (b) Standardized, (c) Studentized deleted residuals; (d) Cook distance; (e) Ratio of variance-covariance matrix; (f) weight leave one out; (g) leverage leave one out; (h) heterogeneity leave one out; (i) R heterogeneity; (k) R Q total; (l) R Q heterogeneity (m); R Q inconsistency and (n) statistic that indicate the effect that deleting each study has on the treatment estimates. - Plots for outlier and influential detection simply and deletion measures (all the above measures) and Q-Q plot for network meta-analysis. - Forward Search algorithm in network meta-analysis. - Forward plots for the monitoring statistics in each step of Forward search algorithm: (a) P-scores; (b) z-values for difference of direct and indirect evidence with back-calculation method; (c) Standardized residuals; (d) heterogeneity variance estimator; (e) cook distance; (f) ratio of variances; (g) Q statistics. - Forward plots for summary estimates and their confidence intervals in each step of forward search algorithm.
