Testing of parallelism of regression lines is discussed and theclassical F-test is compared with the Sen rank test by means of simulations.A rank based multiple comparisons rule for detecting regression lines withdifferent slopes is constructed and asymptotic distribution of the underlyingstatistic is derived. This rule is compared by means of simulations with therule derived from the asumption that the random fluctuations are Gaussian.
