nwrem 1.0.10

Patch release. Works with nwcommands 3.6.0 and later; no change of the Mata library.

Changed

• Help text corrected: speed claim re-timed. The earlier statement that nwrem is 2 to 12 times faster than relevent rested on old timings of two models; it is replaced by timings of 26 October 2026 for five effect sets at 200 to 20,000 events (relevent/nwrem time ratio 0.75 to 36; nwrem is slower for recency effects at up to 1,000 events). README: new Speed section. No change in code or results.

nwrem 1.0.9

Patch release. Works with nwcommands 3.6.0 and later; no change of the Mata library.

Changed

• Help text corrected: references to development scripts and to an internal roadmap removed from the help; the AI-assistance paragraph of NOTICE.md no longer mentions C (the package has no plugin); the README install lines start with nwinstall. No change in code or results; the Mata library is unchanged.

nwrem 1.0.8

Patch release. Works with nwcommands 3.6.0 and later; no change of the Mata library.

Fixed

• covevent() with a two-mode network (missing cells between nodes of the same mode) ended in repeated "initial values not feasible" messages; it is now refused with the common message and error 6088. A covariate network with missing tie values stops with error 416.
• The error message of nwrem without an effect no longer refers to internal development notes.

nwrem 1.0.7

Changed

• Rebuilt for nwcommands (core) 3.6.0: the Mata library is compiled against the core library of 3.6.0 (built with Stata 17) and the package needs nwcommands 3.6.0 or later. No change in results.
• Install lines and the README: nwinstall, everything installs the core and the four model packages in one step. Supported Stata versions: 17 or later, tested with Stata 17 and 18.

nwrem 1.0.6

Fixed: the Mata libraries of the previous release, built with Stata 18, were ignored by Stata 17 (r(3499)). They are now built with Stata 17, which works in Stata 17 and 18. Requires nwrem 3.5.1 or later. Stata 17 or later, tested with 17 and 18. No change to results.

If you have an older install, run ado uninstall nwrem and ado uninstall nwrem first, then reinstall as on https://nwcommands.org/nwrem/install/.

nwrem 1.0.5

Results that change (read before you re-run old fits)

• Events with the same time keep the order in which they stand in the network. Earlier versions ordered tied events by chance (it depended on the random-number generator), so estimates for data with tied event times change and now repeat exactly. Data without tied times are unchanged.

Fixed

• Events with the same time (ties) keep the order in which the network lists them. Before, they were sorted with a tie order that depended on the state of the random-number generator, so the same data could give a different likelihood and slightly (or, with many ties, strongly) different estimates from run to run. Data without tied times were not affected.

nwrem 1.0.4

Changed

• Rebuilt for nwcommands 3.4.0; requires core 3.4.0 or later.
• A fit with effects that are not identified (an exactly collinear effect such as ntdegsnd together with nodsnd and nidsnd, or a standard error above 100) now prints a note under the table and returns the effect names in e(unidentified). Before, the table showed a missing standard error without a warning.

nwrem 1.0.3

Fixed

• Works right after a fresh install: the Mata library is indexed automatically. Before, the first call in a new Stata session could stop with r(3499) "... not found" (or, for nwergm, "class ErgmGraph undefined") until mata mlib index was run by hand.

nwrem 1.0.2

Changed

• The version is shown at the bottom of each help file.

nwrem 1.0.1

Documents the version subcommand in the help file.
