R package tEDM by stscl — release notes from GitHub.

github.com/stscl/tEDM ↗

The temporal half of the stscl EDM pair, tracking its spatial sibling

causal-inferencetime-seriesempirical-dynamic-modelingr-packagecohort-release
◆Current state
tEDM applies empirical dynamic modeling to time series — cross mapping, convergent cross mapping and the logistic map — as the temporal counterpart to spEDM, with which it shares a maintainer and a C++ core. The recent releases are consolidation rather than expansion: index handling in cross mapping corrected, generics taught to accept varying E, k and tau, and the associated paper now cited in the README. Only three releases are visible in the feed.
◆Where it's heading
tEDM moves in lockstep with spEDM. Configurable distance metrics, varying E/k/tau inputs, strict floating-point comparison and the S3 plotting font unification all appear in both packages within days or weeks, as does the maintainer surname correction. The recent balance has tilted toward correcting library and prediction index handling — the kind of repeated attention that suggests the indexing model was the weak point of the shared core.
◆Prediction
Expect tEDM to keep inheriting the shared-core changes spEDM lands, with its own releases staying small and centred on cross-mapping parameter handling rather than new method surface.

◆Recent moves

    Maintainer name corrected, published paper cited

    Housekeeping only: the maintainer surname is corrected from Lv to Lyu for pinyin compliance, and the README and CITATION now point at the published tEDM paper. The same surname correction lands in sibling package spEDM five days later, which is the clearest marker that the two move as one cohort.

    Cross-mapping index handling corrected, generics accept varying E, k, tau

    The substantive release of the three: multispatialccm gains lib-unit specification, and simplex and ic generics accept varying E, k and tau — the same change spEDM shipped in 1.9. Two breaking fixes correct library and prediction index handling in cross mapping, which changes results rather than just the interface.

    Configurable distance metrics for cross mapping

    Cross mapping gains configurable distance metrics, arriving a week ahead of the identical change in spEDM 1.8. Time-delay embedding is adjusted for flexible tau configurations and lib/pred index filtering refined — both breaking, and both in the indexing area this package keeps returning to.
