# EstimatorResult

*class* `qiskit.primitives.EstimatorResult(values, metadata)`

[GitHub](https://github.com/qiskit/qiskit/tree/stable/0.46/qiskit/primitives/base/estimator_result.py)

Bases: `_BasePrimitiveResult`

Result of Estimator.

```python
result = estimator.run(circuits, observables, params).result()
```

where the i-th elements of `result` correspond to the circuit and observable given by `circuits[i]`, `observables[i]`, and the parameter values bounds by `params[i]`. For example, `results.values[i]` gives the expectation value, and `result.metadata[i]` is a metadata dictionary for this circuit and parameters.

**Parameters**

- **values** (*np.ndarray*) – The array of the expectation values.
- **metadata** ([*list*](https://docs.python.org/3/library/stdtypes.html#list)*\[*[*dict*](https://docs.python.org/3/library/stdtypes.html#dict)*]*) – List of the metadata.

## Attributes

### experiments

Experiment data dicts in any inheriting result dataclass.

> **Deprecated since version 0.46.0**
>
> The property `qiskit.primitives.base.base_result._BasePrimitiveResult.experiments` is deprecated as of qiskit 0.46.0. It will be removed in the Qiskit 1.0 release.

### num\_experiments

Number of experiments in any inheriting result dataclass.

> **Deprecated since version 0.46.0**
>
> The property `qiskit.primitives.base.base_result._BasePrimitiveResult.num_experiments` is deprecated as of qiskit 0.46.0. It will be removed in the Qiskit 1.0 release.

### values

Type: `np.ndarray[Any, np.dtype[np.float64]]`

### metadata

Type: `list[dict[str, Any]]`

## Methods

### decompose

`decompose()`

Generate single experiment result objects from self.

> **Deprecated since version 0.46.0**
>
> The method `qiskit.primitives.base.base_result._BasePrimitiveResult.decompose()` is deprecated as of qiskit 0.46.0. It will be removed in the Qiskit 1.0 release.
