NEWS file for the ergm.count package

Changes in version 4.1.2

BUG FIXES

• A number of fixes and corrections to package documentation.

Changes in version 4.1.1

NEW FEATURES

• Default proposals for Binomial, Poisson, Geometric, and also DiscUnif now implement the full DyadGen API for arbitrary dyad-level constraint combinations and TNT proposal weighting.

BUG FIXES

• Vignette's run time is now more predictable.

• Miscellaneous documentation fixes.

OTHER USER-VISIBLE CHANGES

• Term and termalike documentation has been ported to the new documentation system.

• Package tests now use testthat.

• Proposals Poisson, PoissonTNT, PoissonNonObserved, Geometric, GeometricTNT, Binomial, and BinomialTNT have been removed in favour of the more universal Disc and DiscTNT for random and TNT weights.

Changes in version 4.0.2

NEW FEATURES

• A vignette demonstrating the package's functionality has been added.

BUG FIXES

• Package now uses the ergm 4.0 term API, which should result in a nontrivial speedup.

Changes in version 3.4.0

BUG FIXES

• Package has been ported to the ergm 3.10 API changes.

OTHER USER-VISIBLE CHANGES

• Package now Imports statnet.common rather than depending on it.

Changes in version 3.3.0

BUG FIXES

• Package now works when loaded but not attached.

• Test that was failing with ergm 3.6.0 has been fixed.

Changes in version 3.2

NEW FEATURES

• ergm.count now makes use of contrastive divergence in ergm to obtain starting values for the MCMLE.

• Poisson-reference ERGMs now have TNT-style proposal, optimized for sparse networks.

OTHER USER-VISIBLE CHANGES

• The CMP term now adds, rather than subtracts \sum_{(i,j)}\log(y_{i,j}!), whereas 3.1.1 and prior versions did the opposite. This means that higher \theta_{\text{CMP}} represents overdispersion and lower \theta_{\text{CMP}} represents underdispersion.

Changes in version 3.1.1

OTHER USER-VISIBLE CHANGES

• E-mail address and affiliation of the maintainer have been updated.

Changes in version 3.1

THIS IS AN INITIAL RELEASE

• Although this is an initial release, it is depends very heavily on the ergm package version 3.1, and it is thus numbered 3.1.

NEW FEATURES

• A number of reference measures for count data have been implemented. See ? 'ergm.count-package' and ? 'ergm-references' for help.
