Quick release to remove the base R pipe (to maintain backwards compatibility). # probably 1.0.1
The conformal functions int_conformal_infer_*()
were renamed to int_conformal_*()
.
predict.int_conformal_cv()
now returns a .pred
column that is the average prediction from the resampled models. The prediction intervals are centered on these.
Split conformal inference is available using int_conformal_split()
and conformal quantile regression can be used with int_conformal_quantile()
.
Copyright holder changed to Posit Software PBC.
A set of calibration tools were added:
cal_plot_*()
functions.cal_estimate_*()
functions.cal_validate_*()
functions.cal_apply()
can take a calibration model and apply it to a set of existing predictions.Possible calibration tools:
Based on the initial PR (#37) by Antonio R. Vargas, threshold_perf()
now accepts a custom metric set (#25)
Two functions were added to compute prediction intervals for regression models via conformal inference:
int_conformal_infer()
int_conformal_infer_cv()
Max Kuhn is now the maintainer (#49).
Re-licensed package from GPL-2 to MIT. All copyright holders are RStudio employees and give consent.
Fixed a bug with how make_class_pred()
and make_two_class_pred()
validate the levels
argument (#42).
threshold_perf()
now has an explicit event_level
argument rather than respecting the now deprecated yardstick.event_first
global option (#45).
Bumped the minimum required R version to >=3.4.0 to align with the rest of the tidyverse.
Updated to testthat 3e (#44).
class_pred
objects are now comparable and will be ordered by their levels. Equivocal values are generally considered to be the smallest value when ordering. NA
values can be considered smaller if vec_order(na_value = "smallest")
is used.Suggest the modeldata package, which is where the lending_club
dataset has been moved after being removed from recipes.
Use testthat::verify_output()
on a test expecting a specific vctrs error to avoid failure on CRAN if that error changes in the future.
probably has been brought up to date with vctrs 0.2.0. This vctrs update had many function name changes, and required internal refactoring, but there should be minimal external changes.
The one user facing change comes with casting from one class_pred
object to another class_pred
, or to a factor
. Where previously a warning would be thrown if x
had levels that did not exist in to
, an error is now generated. This is consistent with the vctrs behavior when converting from one factor to another.
x <- class_pred(factor("a"))
to <- class_pred(factor("to"))
vec_cast(x, to)
#> Error: Lossy cast from <class_pred> to <class_pred>.
#> Locations: 1
A failing test relying on the R 3.6 change to sample()
has been corrected.
An rlang warning in threshold_perf()
has been fixed.
A small R 3.1 issue with vctrs has been fixed.
