Abstract

The estimation of any biserial correlation coefficient is biased if noise‐like processes are overlaid. We've carried out a computer simulation to study this effect. The effect can be described in a universal way. Additionally, we've varied the type of distribution within the simulation and compared this effect with the effect of noise. Based on this comparison, we've been able to draw some conclusions on the use of biserial correlation coefficients.

The sequential probability ratio test (SPRT) for the correlation coefficient is exaniined in the normal and non-normal situations. I n the latter case, we evaluate the robustness of the normal procedure when sampling from the mixtures of normal distributions. Two models are introduced for this type

Turbulence caused by train motion, heat radiation and wind eddies destroys the coherent nature of the ground effect. Due to upward refraction, only a certain segment of the track contributes to noise emission. Thus, geometrical spreading and refraction govern the process of noise propagation. Noise
