[R] [R-pkgs] sampleSelection 1.0 released

[Arne Henningsen]

Dear All

The recently released version of the sampleSelection package [1] has
the version number 1.0, because we consider the package now to be
mature and feature-complete. Compared to version 0.6 of the
sampleSelection package (which is described in an article in the
Journal of Statistical Software [2]), the new version has, for
instance, following new features:

* estimation of binary-outcome selection models

* probit models, tobit-2 models, and binary-outcome selection models
can now be estimated with observation-specific weights

* predict() methods for calculating unconditional and conditional expectations

* improved/extended residuals() methods

* logLik() methods

* nobs() and nObs() methods

* default df.residual() method works

* removed the deprecated function tobit2()

Any kind of feedback is--as always--very welcome, preferable via R-Forge [3]!

Best regards,
Ott and Arne
