Advanced

Alternative

Defines the alternative hypothesis.

  • The default value is Two-sided. You can modify this value.
  • You can choose from –
  • Two-sided - the distributions are not equal
    • Larger- underlying x distribution is stochastically less than the underlying y distribution.
  • Smaller- underlying x distribution is stochastically greater than the underlying y distribution.

Node Configuration


It allows you to select the instance of the AWS server to provide control over the execution of a task in a workbook or workflow.

Example of One Sample Proportion Test

Consider a dataset containing features like Customer Id, Age, Occupation, Current Balance, Current Month Credit, Current Month Debit, Current Month Balance, Location, and so on.
Location is selected as a feature for the categorical variable.


To add a Unique Value of Feature, follow the steps given below.

  • Click on the Unique Value of Feature in the properties pane. The output Column window is shown.
  • Click Add all unique value. The unique values within the selected feature are shown in the values drop-down option.
  • In value, select the required unique value from the drop-down list.
  • Click Done.

Here, Pune is selected as the Unique Value of the Feature.
Click the vertical ellipsis (  ) and run the node. After the running status is updated click explore to view the test result.
The part of the result page for the One Sample Proportion Test is displayed below.
