  • new feature:
    • new function “aoa”: quantify and visualize the area of applicability of spatial prediction models
    • “minVar” in ffs: Instead of always starting with 2-pair combinations, ffs can now also be started with combinations of more variables (e.g starting with all combinations of 3)
  • bugfix:

CAST 0.3.0

CRAN release: 2018-10-11

CAST 0.2.1

CRAN release: 2018-07-12

  • new feature: Introduction to CAST is included as a vignette.

  • bugfix: minor error fixed in using user defined metrics for model selection.

CAST 0.2.0

CRAN release: 2018-05-03

  • bugfix: ffs with option withinSE=TRUE did not choose a model as “best model” if it was within the SE of a model that was trained in an earlier run but had the same number of variables. This bug is fixed and if withinSE=TRUE ffs now only compares the performance to models that use less variables (e.g. if a model using 5 variables is better than a model using 4 variables but still in the SE of the 4-variable model, then the 4-variable model is rated as the better model).

  • new feature: plot_ffs plots the results of ffs to visualize how the performance changes according to model run and the number of variables being used.
