mlr3inferr (version 0.2.1)

mlr_measures_ci.con_z: Conservative-Z CI

Description

The conservative-z confidence intervals based on the ResamplingPairedSubsampling. Because the variance estimate is obtained using only n / 2 observations, it tends to be conservative. This inference method can also be applied to non-decomposable losses.

Point Estimation

For the point estimation, only the first repeats_out resampling iterations will be used, as the other resampling iterations are only used to estimate the variance. This is respected when calling $aggregate() using a standard (non-CI) measure.

Parameters

Only those from MeasureAbstractCi.
