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: show that a non-finite number (positive infinity, negative infinity, or Not-a-Number, NaN) is stored as missing, whichever of three routes brings it into a column: a value written in the specification, a value read from the source, or a value returned by a study calculation.
Input: one spec.yaml over a subject-level dataset whose numeric
fields POSITIVE_INFINITY, NEGATIVE_INFINITY, and NOT_A_NUMBER
each hold one non-finite value.
Columns: every one of these is stored as missing.
YAML_PINF,YAML_NINF, andYAML_NANwrite positive infinity, negative infinity, and NaN directly inspec.yaml.SOURCE_PINF,SOURCE_NINF, andSOURCE_NANcopy them fromPOSITIVE_INFINITY,NEGATIVE_INFINITY, andNOT_A_NUMBER.FUNCTION_PINF,FUNCTION_NINF, andFUNCTION_NANtake them from the study calculationnumeric_constant. Its contract allows a missing result; a calculation that may not return one fails the run when it returns a non-finite value.
Note: a quoted spelling such as '.inf' remains text unless
converted to a numeric type.
Engines: numeric_constant belongs to the ordinary installed packages
in rust/tests/project-programs. The function file
functions/numeric_constant.yaml declares it once, with its inline tests, and
names the Python and R implementations, which return the same three
non-finite constants.
