Measurement of extreme drag coefficients of building models

Journal of Wind Engineering and Industrial Aerodynamics, 1986
Abstract Several rigid building models with different cross-sections and with different heights were investigated in a boundary-layer wind tunnel. Velocity profiles and the corresponding turbulence spectra were simulated approximately according to typical full scale terrains.

An extremely strange observation on the equations for calculation of correlation coefficient

European Journal of Drug Metabolism and Pharmacokinetics, 2003
Various equations are used to calculate the correlation coefficient, these equations are presumed equally. However we find the extraordinary results when using r = square root of ((sigma(ŷi - y)2) / (sigma(yi - y)2)) and r2 = (sigma(yi - y)2 - sigma(yi - ŷi)2) / (sigma(yi - y)2) to calculate the correlation coefficient, for example, a line within 95 ...

Estimating the extremal coefficient: a comparison of methods

2018
Tail dependence is an important issue to evaluate risk. The multivariate extreme values theory is the most suitable to deal with the extremal dependence. The extremal coefficient measures the degree of dependence between the marginals of max-stable distributions, a natural class of models in this framework. The estimation of the extremal coefficient is
