Test Options (One-Sample Nonparametric Tests)
- Significance level
- This specifies the significance level (alpha) for all tests. Specify a numeric value between 0 and 1. 0.05 is the default.
- Confidence interval (%)
- This specifies the confidence level for all confidence intervals produced. Specify a numeric value between 0 and 100. 95 is the default.
- Excluded Cases
- This specifies how to determine the case basis for tests.
- Exclude cases test by test
- Records with missing values for a field that is used for a specific test are omitted from that test. When several tests are specified in the analysis, each test is evaluated separately.
- Exclude cases listwise
- Records with missing values for any field that is named on the Fields tab are excluded from all analyses.
- Monte Carlo Sampling
-
When certain parameters of the distribution have to be estimated from the sample, the Kolmogorov-Smirnov test no longer applies. In these instances, the Lilliefors test statistic can be used to estimate the p-value by using the Monte Carlo sampling for testing normality with mean and variance unknown. The Lilliefors test applies to the three continuous distributions (Normal, Exponential, and Uniform). Note that the test does not apply if the underlying distribution is discrete (Poisson). The test is only defined for one-sample inference when the corresponding distribution parameters are not specified.
- Set custom seed
- When enabled, this setting provides the option of resetting the random Seed value that is used for Monte Carlo sampling. The value must be a single integer between 1 and 2,147,483,647 (the default value is 2,000,000). By default, the setting is not enabled, which produces a random seed value.
- Number of samples
- Resets the number of Monte Carlo sampling replicates that are used by the Lilliefors test. The value must be a single integer between 100 and the largest integer. The default value is 10,000.
- Simulation confidence level (%)
- Resets the Kolmogorov-Smirnov test's estimated confidence interval level. The value must be a single value between 0 and 100. The default value is 99.
