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: fix the order of the output rows: two sort terms, missing values sorting as the lowest value, and a stable order for ties.
Input: one spec.yaml over one adverse-event dataset AE,
stored out of order, carrying subject, sequence number, decoded term
(AEDECOD, copied through unchanged), and analysis start day
(AESTDY), which may be missing.
Order:
- first by analysis start day (
AESTDY), ascending, so missing days come before every present day; - then, among rows on the same day or both missing a day, by
sequence number (
AESEQ), descending.
Note: a missing value sorts as lower than every present value: first in an ascending sort and last in a descending one, unless the order states where missing values go. Rows equal on both terms keep their input order.
