cropyieldmodel 0.1.0

Initial version of the regional crop-yield modelling package, released under the name cropyieldmodel.

Includes six base estimators, a regularized ensemble, chronological model comparison, empirical intervals, area-weighted aggregation, and Poland and synthetic examples. The source archive includes function documentation and rendered tutorials.

The project is now named YieldLag. See YieldLag releases for current versions. This historical archive retains its original R package name.

The local R 4.5.2 package check and four-platform GitHub check matrix passed. Archive checksums and verification metadata accompany the source package. The bundled Poland example is a retrospective benchmark with fixed area weights; code and data terms are documented separately.
