Syntax Elements
- database
- The database containing the table to analyze.
- tablename
- The table containing the columns to analyze. It must reside in the database indicated by the database parameter.
- firstcolumn
- The column to analyze. It must reside in the table indicated by the tablename parameter.
- binomialprobability
- [Optional] The binomial probability.
- Disallowed with teststyle=sign.
- Default: 0.5
- exactmatches
- [Optional] How to handle exact matches:
| exact_matches |
Description |
|---|
| 0 |
Discard exact match. |
| Positive |
Put exact match with values greater than or equal to zero. |
| Negative (default) |
Put exact match with values less than or equal to zero. |
- Disallowed with teststyle=sign.
- fallback
- [Optional] Whether to give the output table the FALLBACK attribute.
- Default: false
- gensqlonly
- [Optional] True returns the SQL for the function as a result set but does not run it.
- False runs the SQL for the function but does not return it as a result set.
- Default: false
- groupby
- [Optional] The input table columns for which to separately analyze each value or combination of values.
- Default behavior: Input is not grouped.
- multiset
- [Optional] Whether to give the output table the MULTISET attribute.
- Default: false
- outputdatabase
- [Optional] The name of the database to contain the analysis results table.
- outputtablename
- [Optional] The name of the table to store the analysis results.
- Default behavior: Function returns results as a result set but does not create an output table.
- secondcolumn
- [Optional] The second column to analyze.
- Required with teststyle=binomial.
- Disallowed with teststyle=sign.
- singletail
- [Optional] Whether the test is single-tailed.
- Specify true only with binomialprobability=0.5.
- Default: false (test is two-tailed)
- statsdatabase
- [Optional] The database where the statistical test metadata tables are installed.
- Default behavior: The function searches the source database for these tables.
- teststyle
- [Optional] Binomial test or sign test.
- Default: binomial
- thresholdprobability
- [Optional] The threshold (alpha) probability, below which the null hypothesis is rejected.
- Default: 0.05
