The final list is (consensus shortlist + force) - drop, then
intersected with keep when given. force is allowed only for
variables that reached binning; a variable failed for IV_SUSPICIOUS
(the leakage ceiling) and a derived __sp flag under
allow_derived_final = FALSE are refused unless override = TRUE.
reason is one string for every variable named, or a character vector
named by variable.
Usage
scr_classing_choose(
lab,
keep = NULL,
drop = NULL,
force = NULL,
reason = NULL,
override = FALSE
)Arguments
- lab
An object from
scr_coarse_classing().- keep
Variables to keep (restricts the final list).
- drop
Variables to remove from the final list.
- force
Variables to add to the final list.
- reason
Mandatory when
droporforceis given.- override
Allow a refused
force.
