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.

columnofinterest

A numeric input table column whose values have a normal distribution. It must reside in the table indicated by the tablename parameter.

columns

[Optional] Only if teststyle=ks, the input table column that represents a categorical variable with two values that indicate the distribution to which the columnofinterest belongs.

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.

Parameter not valid when teststyle=s.

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.

When teststyle=s, the groupby parameter is limited by one groupby column or none.

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.

overwrite

[Optional] Whether to drop the output tables before creating new ones.

Default: true

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] The test style, which is one of the following:

Option	Test Style
ks (default)	Kolmogorov-Smirnov
l	Lilliefors
sw	Shapiro-Wilk
p	D'Agostino and Pearson
s	Smirnov

thresholdprobability

[Optional] The threshold (alpha) probability, below which the null hypothesis is rejected.

Default: 0.05
