Some of the slower routines now print progress reports via cli.
The package now works under ergm 4.12.0.
Standard error calculation has been made slightly more robust.
Some bibliographic references in the documentation have been updated.
triangles() EgoStat has been added.
The package now works under ergm 4.9.0.
EgoStat esp, and function as.egor.network() now run much faster.
Changes in term naming for the degree term for consistency with ergm 4.8.
mixingmatrix() method for egor objects now behaves more consistently with the method in network.
Categorical EgoStats now base their levels selection on egos only; this means that selectors LARGEST and SMALLEST now work consistently with ergm. If the alters have levels that egos do not, a warning is issued.
An EgoStat for absdiffcat() has been added.
degreedist() has been fixed.
logLik() method for ergm.ego objects has been added; it produces an informative error message.
Documentation fixes.
ergm.ego() now has a basis= argument. So does simulate.ergm.ego(), for consistency (as an alias for the popsize= argument).
simulate.ergm.ego()'s popsize= argument can now be a network object, enabling simulation from any starting network.
gof.ergm.ego(GOF="degree") now handles the case in which the observed or simulated degree distribution is dense and the LHS network is small more gracefully.
gof.ergm.ego() was scrambling the the order of ESP terms.
simulate.ergm.ego() is now more robust to models with offsets and extreme “dropped” statistics.
ergm.ego() (via control.ergm.ego(ppopsize=)) and simulate.ergm.ego(popsize=) can once again take data.frames and tibbles to specify the pseudopopulation network composition directly.
simulate.ergm.ego() now preserves some of the attributes attached by simulate.ergm() to the statistics matrix, including "monitored".
simulate.ergm.ego() no longer supports ergm.ego objects fit under under ergm < 4.
Documentation fixes, particularly for compatibility with ergm 4.2.
Summary for ergm.ego fits now displays the original call rather than the instrumental ergm() call.
control.ergm.ego() praameter ignore.max.alters= now defaults to TRUE, since simulation studies (Krivitsky, et al. 2020) showed that they did more harm than good.
This package now uses the egor package's egor class for data storage and manipulation. A converter as.egor.egodata() is provided.
ergm.ego() now supports complex survey designs set on egor objects.
ergm.ego() and the summary methods can now fit triadic effects (gwesp, esp, transitiveties) when alter-alter ties are available.
ergm.ego() can now handle missing alter attributes in some circumstances, and provided they are missing completely at random.
A number of new egostats have been implemented, including gwdegree
A number of improvements to the goodness-of-fit routines.
snctrl() UI for specifying control parameters is supported.
Curved ERGMs are now supported; this capability should be considered experimental, as uncertainty estimates have not been rigorously derived.
For nonscaling statistics such as meandeg, standard errors can now be computed.
Network size adjustment can now be disabled during fitting.
Various fixes to degreedist(), mixingmatrix(), and other methods.
The function that was previously as.network.egodata() for constructing an empty network having the same composition as the egocentric dataset has been superseded by template_network().
Manually specified pseudo-population is handled better.
degreedist() method for egocentric data now defauts to not making plots.
mixingmatrix() method for egocentric data now returns a table.
predict.ergm.ego, a predict method for ergm.ego has been implemented. (Thanks, Michał Bojanowski.)
Nonscaling statistic meandeg has been added.
EgoStat.* functions no longer need to be exported, reducing namespace pollution.
ergm.ego now detects when a coefficient has been
dropped by ergm due to the statistic having
an extreme value and subsets the variance matrices accordingly.
control.ergm.ego now calls match.arg on
ppopsize only if ppopsize is of class
character. This allows ppopsize to be of class
network when calling
control.ergm.ego.
A more thorough search mechanism for EgoStat.* functions no longer requires them to be exported.
ergm's new nodal attributes user interface has been extended to ergm.ego.
mixingmatrix.egodata and degreedist.egodata now have an option to ignore sampling weights.
Simulation frmo an ergm.ego fit now inherints the constraints.
It is now possible to specify the (pseudo)population network temlate directly by passing it to control$ppopsize.
It is now possible to infer main effects (nodefactor and nodecov) when the attribute has only been obseved on the egos.
A wide variety of minor bugs has been fixed. See commit log and issue tracker for details.
A number of robustifications have been made.
ergm.ego now produces sensible error messages when terms have alter categories that egos do not.
Chad Klumb has been added as a contributor.
gof.ergm.ego's default MCMC.interval is now the MCMC.interval of the ergm fit scaled by the ratio between the fit's MCMC.samplesize and GoF control's nsim.
gof.ergm.ego now only calculates GOF for degree values up to twice the highest observed in the data or 6, whichever is higher with an additional category to catch the higher values.
mm term has been implemented.
degreedist now has an option to
not plot, and returns the calculated degree distribution
(invisibly, if plotting).
offset terms are now handled.
More EgoStat now handle more options that their
ergm counterparts do.
ergm.ego's ppopsize control parameter and
simulate method for ergm.ego's popsize
argument now take a data frame of egos to use as the
pseudopopulation.
Package now works with ergm
3.9.
degreedist now handles
sampling weights correctly, and has been fixed in other ways.
Bootstrap and jackknife now handle one-dimentional stats correctly.
mixingmatrix.egodata now handles ego ID column names
other than vertex.names. Thanks to Deven Hamilton for
reporting this bug. Non-numeric ego IDs are also handled correctly.
mixingmatrix.egodata no longer rounds the row
probabilities before returning when called rowprob=TRUE.
degreedist.egodata is now an
egodata method of degreedist.
This is the initial public release.
