Guedes Soares, C. e Henriques, A.C. (1994), “On the Statistical Uncertainty in Long Term Predictions of Significant Wave Height”, Proceedings of the 12th Offshore Mechanics and Artic Engineering Conference (OMAE), New York, Vol. II, pp. 65-75
This work examines some aspects involved in the estimation of the parameters of the probability distribution of significant wave height, in particular the homogeneity of the data sets and the statistical methods of fitting a distribution to data. More homogeneous data sets are organised by colecting the data on a monthly basis and by separating the simple sea states from the combined ones. The parameters of the fitted distribution are estimated by the method of maximum likelihood, of regression and of the moments. The uncertainty involved in estimating the probability distribution with the tree methods is compared with the one that results from using more homogeneous data sets and it is concluded that the uncertainty involved in the fitting procedure can be more significant.
