## Sub-layer

**L1_5_C_stationarity_tests**

## Axis metadata

- Sweepable: False
- Status: operational

## Operational status summary

- Operational: 3 option(s)
- Future: 0 option(s)

## Options

### `predictors_only`  --  operational

Run stationarity tests on predictor columns only.

Restricts L1.5.C tests to the ``predictors_only`` column subset.

This option configures the ``stationarity_test_scope`` axis on the ``L1_5_C_stationarity_tests`` sub-layer of L1.5; output is emitted under ``manifest.diagnostics/l1_5/L1_5_C_stationarity_tests/`` alongside the other selected views.

**When to use**

When the target is known stationary (growth rates, returns) and only the predictors are uncertain.

### `target_and_predictors`  --  operational

Run stationarity tests on every column.

Restricts L1.5.C tests to the ``target_and_predictors`` column subset.

This option configures the ``stationarity_test_scope`` axis on the ``L1_5_C_stationarity_tests`` sub-layer of L1.5; output is emitted under ``manifest.diagnostics/l1_5/L1_5_C_stationarity_tests/`` alongside the other selected views.

**When to use**

Default; comprehensive audit that catches surprises in either target or predictors.

### `target_only`  --  operational

Run stationarity tests on the target column only.

Restricts L1.5.C tests to the ``target_only`` column subset.

This option configures the ``stationarity_test_scope`` axis on the ``L1_5_C_stationarity_tests`` sub-layer of L1.5; output is emitted under ``manifest.diagnostics/l1_5/L1_5_C_stationarity_tests/`` alongside the other selected views.

**When to use**

Confirming the L2-applied tcode rendered the target stationary.
