Corrected bug in
gw in relation of optimization methods.
residuals.gw S3 method includes now the possibility of parallel computing in order to construct the simulated envelope.
GWRM.fit is now
gw. The default algorithm to find ML-estimates is L-BFGS-B after nlm and Nelder-Mead previous optimizations; it provides SE estimates of all the parameters of the model.
k=1 argument corresponds to the classical Waring regression model.
GWRM.display is now the S3 method
GWRM.add is now included in the new S3 method
add1.gw and may be used through
GWRM.stats is now the S3 method
residuals.gw S3 method has been included to validate the fits with the analysis of residuals.
