Note on the estimation of crossing intensity for Laplace moving average
Artikel i vetenskaplig tidskrift, 2011
In this note upcrossing intensity of a level u by a non-Gaussian process-the Laplace Moving Average (LMA)-is estimated by means of a saddle point approximation of Rice's formula. A LMA-process is defined by power spectral density, skewness and kurtosis parameters. The method is illustrated by measurements of sea surface elevation and stresses in a vessel.
