Statistical comparison of the slopes of two regression lines: A tutorial.

Abstract

Comparing the slopes of two regression lines is an almost daily task in analytical laboratories. The usual procedure is based on a Student's t-test although literature differs in whether the standard errors of the slopes or the standard errors of the regressions should be employed to get a pooled standard error. In this work fundamental concepts on the use… (More)
