1. Modeling synthetic aperture radar image data
In this thesis we study maximum likelihood estimation (MLE) of the roughness parameter of the G 0 A distribution for speckled imagery (Frery et al., 1997). We discover that when a certain criteria is satisfied by the sample moments, the likelihood function is monotone and MLE estimates are infinite, implying an extremely homogeneous region. We implement four

2. Modelos gaussianos geoestatísticos espaço-temporais e aplicações / Space-time geostatisticals guassian models and aplications
The specification of space-time covariance functions is one of the possible strategies to model processes observed at different locations and time points. Such functions can define separable and non-separable processes and must attend the condition of positivedefiniteness. Among the strategies to obtain such valid functions are the ones suggested by Cressie
