                         distribution has been widely used in the modelling of data 
                         corrupted by speckle noise (SAR images). We focus on point 
                         estimation and on signalized likelihood ratio tests. As far as 
                         point estimation is concerned, the numerical evidence presented in 
                         the paper favors the Cox and Reid's adjustment (1987), and in what 
                         concerns signalized likelihood ratio tests, the results favor the 
                         approximation to Barndorff-Nielsen's adjustment based on the 
                         results in Fraser and Reid (1995). An application to real 
                         synthetic aperture radar imagery is presented.",
