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.
Each subject and reference day receives the measurement nearest that day.
BASE supplies the subject identifier ID and reference day REF;
SRC supplies candidate measurement days and their text values.
VALUE is the selected measurement, and DIST is the absolute difference
between its day and REF. For S1, reference day 10 selects b on day 11,
while reference day 3 selects a on day 2 from the same candidates.
For S2, days 9 and 11 are equally close to reference day 10; the first
record selects c. A candidate with no day is excluded. S4 has no
candidate, so both selected values are missing. The unmatched S3
candidate contributes no output row.
