CHANGES IN SpatialExtremes VERSION 2.0-7 BUG FIXES o Fix a bug in the (exact!) simulation from the Schlather max-stable process. o Fix a bug in how to handle NA values in the prediction CHANGES IN SpatialExtremes VERSION 2.0-6 BUG FIXES o Minor modification to suppress warnings with a new release of R. CHANGES IN SpatialExtremes VERSION 2.0-5 BUG FIXES o Fix a bug with the simulation for the geometric model. Thanks to Zhuo Wang for finding it! CHANGES IN SpatialExtremes VERSION 2.0-4 NEW FEATURES o Exact simulation for max-stable processes are now fully implemented. o Parallelization is used for computing pairwise likelihood---should be faster (finally). CHANGES IN SpatialExtremes VERSION 2.0-3 NEW FEATURES o Concurrence probabilities and cells are now implemented. o Exact simulation for max-stable processes are (partially) implemented. CHANGES IN SpatialExtremes VERSION 2.0-0 SIGNIFICANT USER-VISIBLE CHANGES o There is only one methodology to compute standard errors; hence the arguments std.err.type is deprectated. NEW FEATURES o Missings values (NA's) are now available for max-stable and latent models ! BUG FIXES o Fix a bug with the mean of the prior distribution assumed on the regression parameters for the latent variable approach. CHANGES IN SpatialExtremes VERSION 1.9-0 SIGNIFICANT USER-VISIBLE CHANGES o The memory allocation is now much improved, your computer should not freeze anymore ;-) NEW FEATURES o Conditional simulations from various max-stable models (not max-linear models) are available. o Simulation from the extremal-t process are now performed using its spectral characterization o Different (but still naive) approaches for simulating Brown-Resnick processes are implemented BUG FIXES o Fix a bug with the latent variable model that might crash R o Fix a bug with temporal trends CHANGES IN SpatialExtremes VERSION 1.8-1 SIGNIFICANT USER-VISIBLE CHANGES o The parameter "sill" is now called "nugget" to avoid confusion. More precisely, we now have nugget = 1 - sill, so if one wants no nugget effect just set nugget = 0. NEW FEATURES o Model checking for the copula based models is now implemented --- similar to the plot.maxstab function o It is now possible to simulate from copula based models o The package now uses openmp as much as possible! BUG FIXES o Fix a bug with the Student-t copula model o Fix a bug with standard errors and 3d Smith model CHANGES IN SpatialExtremes VERSION 1.8-0 SIGNIFICANT USER-VISIBLE CHANGES o Improvement of the simulation technique for Brown-Resnick processes. NEW FEATURES o (Approximate) conditional simulations of unit Frechet max-stable random fields is implemented. o The copula approach is now available --- use with caution! o Max-linear models are now available. BUG FIXES o Fix a bug with model selection. CHANGES IN SpatialExtremes VERSION 1.7-0 SIGNIFICANT USER-VISIBLE CHANGES o Update contact info: now in Montpellier! o A new function ''latent'' for Bayesian hierarchical models BUG FIXES o Fix a bug in simulating Brown-Resnick processes CHANGES IN SpatialExtremes VERSION 1.6-0 SIGNIFICANT USER-VISIBLE CHANGES o The extremal t model is now available --- including simulation. Simulations on a grid might be really long though. o Model checking for fitted max-stable processes is easier as a method for plotting object of class "maxstab" is implemented. o "fitspatgev" and "fitmaxstab" now allow for "temporal" covariates, for example a linear trend can be put for the location parameter. NEW FEATURES o Simulation of Brown-Resnick processes are available but should *NOT* be considered as stable! o Computation of the empirical variogram is implemented o The fitting and simulation of max-stable processes is now much faster. o The circulant embedding method is now implemented. BUG FIXES o Fix a bug when using temporal covariates. o Fix a bug in simulating Gaussian random fields having a powered exponential covariance function through the turning bands method. o The parametrization of Brown-Resnick processes was not consistent throughout the code. Now fixed. CHANGES IN SpatialExtremes VERSION 1.5-1 BUG FIXES o Fix a bug in computing the standard errors for the geometric gaussian model (marginal part) CHANGES IN SpatialExtremes VERSION 1.5-0 SIGNIFICANT USER-VISIBLE CHANGES o The 'map' and 'condmap' functions now allow covariates o fitmaxstab allows weights in the pairwise likelihood o predict will display standard errors if possible NEW FEATURES o Brown-Resnick processes are available o The generalized Cauchy correlation function is available o New function 'lsmaxstab' that wraps 'fitcovariance' and 'fitcovmat' and is similar to 'fitmaxstab' but uses least squares o Composite version of the BIC is available o The standard errors are now computed without the use of the finite difference based estimate of the Hessian matrix DEPRECATED & DEFUNCT o The 'fitcovmat' and 'fitcovariance' will be removed soon as the new 'lsmaxstab' wraps them BUG FIXES o Fix a bug in simulating smith's max-stable process on a grid
