Argument Category Description
ValueColumn Required Specifies the name of the input table column that contains the values of the sample data set.
Tests Optional Specifies one to four tests to perform. A test can be:
  • 'KS' (Kolmogorov-Smirnov test)
  • 'AD' (Anderson-Darling test)
  • 'CHISQ' (Pearson's Chi-squared test)

By default, the function runs all of the preceding tests.

Distributions Optional Specifies the reference distributions (which must be continuous) and their parameters. The possible distribution and parameters values for continuous distributions are in the table, Continuous Distributions and Parameters, of the Arguments section of the function: Hypothesis-Test Mode. By default, the function uses these distributions:
  • Beta
  • Cauchy
  • CHISQ
  • Exponential
  • F
  • Gamma
  • Lognormal
  • Normal
  • T
  • Triangular
  • Uniformcontinuous
  • Weibull
GroupByColumns Optional Specifies the names of the input table columns that contain the group identifications over which to run the test. The function can run multiple tests for different partitions of the data in parallel. If you omit this argument, then specify PARTITION BY 1 and omit the GROUP BY clause in the second ON clause.
MinGroupSize Optional Specifies the minimum group size. The function ignores groups smaller than the minimum size when calculating statistics. The default value is 50.
NumCell Optional Specifies the number of cells that you want to make discrete in a continuous distribution. The cell_size must be greater than 3 if distribution is NORMAL; otherwise, it must be greater than 1. The quotient min_group_size/cell_size cannot be less than 5. The default value is 10.
Top Optional Specifies the number of the top matching distributions for the function to output. The default value is 1.
