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
README.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: demonstrate the per-record bindings of an aggregation:
convert each record's date to an integer day count with to_epoch_day,
then summarize the integers.
Input: exposure records with sequence numbers (EXSEQ) and
start dates (EXSTDT). Only the record with sequence number 1 becomes
an output row.
Variables:
EXSEQ: the exposure sequence number, carried through.EXSTDY: the exposure start date as a count of days since 1970-01-01 (zero on that day, negative before it), blank when the start date is missing. It is not a day counted from a reference start.
Note: each matching exposure record's date is turned into its day
count first, so the summary works on plain integers and never on dates.
The summary then keeps the value of the one record with the row's
subject and sequence number (ONLY); a second matching record would
stop the run.
