What is cTMed?

Continuous-time mediation effects get standardized centrality, six years into steady patch work

cTMed computes direct, indirect and total effects for continuous-time mediation models, with delta-method, Monte Carlo and bootstrap variants of each. Development is a long run of patch releases from the jeksterslab account, roughly every two months, each adding a function or two. The latest adds standardized centrality measures and allows a diagonal sigma across ten standardized estimators.

What is nflreadr?

The nflverse data loader, whose releases are dictated by the NFL calendar and CRAN's archive policy

nflreadr is the data access layer of the nflverse, wrapping cached downloads of play-by-play, roster, contract, charting and stats releases. Its growth phase peaked with 1.3.0, which added participation data, contracts, weekly rosters, officials and the players endpoint in a single release. Since then the work has been consolidation: 1.5.0 moved to v2 players data and reorganized player stats behind nflfastR's calculate_stats() with a summary_level argument, and 1.5.1 hard-deprecated qs file support after that package was removed from CRAN in January 2026.

Continuous-time mediation effects get standardized centrality, six years into steady patch work

◆ Current state

cTMed computes direct, indirect and total effects for continuous-time mediation models, with delta-method, Monte Carlo and bootstrap variants of each. Development is a long run of patch releases from the jeksterslab account, roughly every two months, each adding a function or two. The latest adds standardized centrality measures and allows a diagonal sigma across ten standardized estimators.

◆ Where it's heading

The package is filling out a matrix rather than changing shape: for each effect type there is a delta-method, a Monte Carlo and a bootstrap path, and each release closes another cell. The 2025 releases were largely externally forced — an Armadillo 15.0.x transition at CRAN, a citation addition after the Psychological Methods paper landed — which suggests the statistical core has been settled since the 1.0.6 standardization revision.

◆ Prediction

The diagonal-sigma option has now reached the standardized estimators; extending it to the remaining unstandardized variants is the obvious next cell to fill.

The nflverse data loader, whose releases are dictated by the NFL calendar and CRAN's archive policy

◆ Current state

nflreadr is the data access layer of the nflverse, wrapping cached downloads of play-by-play, roster, contract, charting and stats releases. Its growth phase peaked with 1.3.0, which added participation data, contracts, weekly rosters, officials and the players endpoint in a single release. Since then the work has been consolidation: 1.5.0 moved to v2 players data and reorganized player stats behind nflfastR's calculate_stats() with a summary_level argument, and 1.5.1 hard-deprecated qs file support after that package was removed from CRAN in January 2026.

◆ Where it's heading

Two external clocks drive this package and neither is under its control. Feature releases land before the NFL season opens — 1.5.0 says so explicitly — and breaking changes are timed to that window. The other clock is CRAN's: losing the qs dependency forced a serialization format out of the package entirely, leaving parquet, rds and csv. The upstream coupling to nflfastR is tightening too, with player and team stats now sourced from its calculation functions rather than computed here.

◆ Prediction

The pattern of a pre-season consolidation release is well established, so the next substantive version is likely timed to the following season's opener rather than to any internal roadmap.
