yamaa As a clinical trial statistician or programmer, answer two short questions in Your review: the task and the inputs and outputs. Agreeing with both approves this benchmark; disagreeing with either needs a comment. Propose a fix with the Edit button on any source file, or add it to your comments.
We suggest spending no more than 5 minutes on a review. The other tabs beside Your review are background for assessment, not under review.
Summary
EditUnder reviewWhat this benchmark meansREADME.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: pin the lookup filter machinery: a filter that reads the current planned visit and so changes which donor record a lookup resolves to, with qualified donor fields, an ordering, and keep-last selection.
Input: PLAN carries the planned visits per subject; LB
carries lab records, one with a missing result and one outside the
planned visit list.
Lookup: the DONOR intermediate implements
last-observation-carried-forward. For each planned visit it keeps the
subject's latest lab record whose result is present and whose visit
number does not exceed the planned visit's. The filter compares each
lab record with the current planned visit's number while the lab fields
stay qualified with the lookup dataset; the eligible records sort by
visit number and the last is kept. A record with a missing result never
qualifies, so its planned visit carries the earlier value forward; a
lab record at an unplanned visit still qualifies by its visit number
and can serve a later planned visit. A planned visit earlier than every
lab record with a result finds no donor, so its result and day are
missing.
Columns: VISIT names the planned visit at visit number
VISITN; the carried-forward lab result and day land in AVAL and
LBDY.
