Bland–Altman plot
A Bland–Altman plot (difference plot) in analytical chemistry or biomedicine is a method of data plotting used in analyzing the agreement between two different assays. It is identical to a Tukey mean-difference plot,[1] the name by which it is known in other fields, but was popularised in medical statistics by J. Martin Bland and Douglas G. Altman.[2][3]
Not to be confused with Estimation statistics § Gardner–Altman plot.Notes[edit]
A similar method was proposed in 1981 by Eksborg.[7] This method was based on Deming regression—a method introduced by Adcock in 1878.
Bland and Altman's Lancet paper [3] was number 29 in a list of the top 100 most-cited papers of all time with over 23,000 citations.[8]
