“…It has been recommended [5] that the linear-regression procedures used in this paper should be restricted to those cases where the correlation coefficient (r) exceeds 0.99. Similarly it has been suggested [6] that the range of values used is adequate when the standard deviation of the comparative method values (SDx) is greater than seven times Syx. The correlation coefficient and the ratio SDx/Syx are related [7].…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
