In statistics, a Galbraith plot (also known as Galbraith's radial plot or just radial plot), is one way of displaying several estimates of the same quantity that have different standard errors.〔 〕 It can be used to examine heterogeneity in a meta-analysis, as an alternative or supplement to a forest plot. A Galbraith plot is produced by first calculating the standardized estimates or ''z''-statistics by dividing each estimate by its standard error (SE). The Galbraith plot is then a scatter plot of each ''z''-statistic (vertical axis) against 1/SE (horizontal axis). Larger studies (with smaller SE and larger 1/SE) will be observed to aggregate away from the origin.〔(University of York, Department of Health sciences MSc course material )〕 == See also == * Plot * Funnel plot 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Galbraith plot」の詳細全文を読む スポンサード リンク
