On the Sensitivity of a Regression Coefficient to Monotonic Transformations
提出一种方法，用于检查单调变换是否可能改变回归系数的符号，帮助研究者检验关键回归系数的稳健性。
This note presents a procedure which enables the user to check whether a monotonic transformation can change the sign of a regression coefficient. One possible use of this procedure is to examine the robustness of key regression coefficients.
