alpha property
Alpha overrides the 0.05 two-tailed significance threshold when it lies strictly between 0 and 1; anything else leaves the default in place.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
num? alpha;
