Dummy Regressor is useful to provide a sanity check and to compare performance against actual Regressors. **Interfaces:** [Estimator](../estimator.md), [Learner](../learner.md), [Persistable](../persistable.md) **Data Type Compatibility:** Categorical, Continuous, Resource ## Parameters | # | Name | Default | Type | Description | |---|---|---|---|---| | 1 | strategy | Mean | Strategy | The guessing strategy to employ when making predictions. | ## Example ```php use Rubix\ML\Regressors\DummyRegressor; use Rubix\ML\Other\Strategies\Percentile; $estimator = new DummyRegressor(new Percentile(56.5)); ``` ## Additional Methods This estimator does not have any additional methods.
