In clinical trials where the treatment groups correspond to increasing dosages of a substance and the outcome is the possibly right-censored time to a certain event, it is desirable to test for increases or decreases in survival times with increasing dose. Furthermore, it may be of interest to study

โฆ Synopsis
A number of studies have hypothesised certain economic behaviour to be hysteretic, but few have actually been able to establish hysteretic behaviour in the data. This is because of the lack of an e ective test for hysteresis. This paper compares and contrasts two new measures of hysteretic behaviour, designed explicitly for detecting hysteresis in economic systems. Using Monte Carlo techniques, we show that one has considerably more power than the other against nonlinear, cyclical or multiple equilibria alternatives in the presence of random disturbances. The key properties of this measure appear to be functional form independence and rate independence.
