ValueColumn
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)

Default: 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, in Hypothesis-Test Mode Arguments. Default: All of 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, 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. Default: 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. Default: 10.
Top
[Optional] Specifies the number of the top matching distributions for the function to output. Default: 1.
