T-Test

A Callable for performing T-Test on two columns and returning its results.

Definition

class controller.callable.transformer.TTest(self, column1: str, column2: str, output_names: list[str], output_list: list[str])

Callable name:

t_test

Callable type:

Transformer

Parameters:

column1 (ColumnReference) – A column reference where the values in the column are used as the first group in the T-Test.
column2 (ColumnReference) – A column reference where the values in the column are used as the second group in the T-Test.
output_name (list[str]) – The names of the new columns containing the Callable outputs.
output_list (list[str]) – A list of columns to return.

Parameters

column1

A column reference where the values in the column are used as the first group in the T-Test.

Type:: ColumnReference
Required:: True
Choices:: All columns in the target DataFrame

column2

A column reference where the values in the column are used as the second group in the T-Test.

Type:: ColumnReference
Required:: True
Choices:: All columns in the target DataFrame, except the column selected in column1

output_name

The names of the new columns containing the Callable outputs.

Type:: list[str]
Required:: True

output_name[0] stores the t-statistic.
output_name[1] stores the p-value.

output_list

A list of columns to return.

Type:: list[str]
Required:: True
Choices:: All columns in the target DataFrame, plus the new columns created by this Callable

Output

A DataFrame is returned where it contains all columns specified in the output_list, potentially including new columns with the names <callable_id>.<output_names>.
