.... These methods consist of fitting a parametric joint probability distribution to two or three mode amplitudes from an Empirical Orthogonal Function (EOF) analysis. The parametric method is intended for and most used when statistical extrapolation is required, i.e., the duration of available data is shorter than...

... unconservative fatigue life estimates. The joint distribution of the last two mode amplitudes is analyzed and found to be polar. Therefore, the three mode amplitudes are mapped to a cylindrical coordinate system, and it is found that cylindrical binning is more efficient, by a factor of more than 2, as compared...
