## 🚀 **Quick Start**

### **Installation**

```bash
pip install lrdbench
```

### **Basic Usage**

```python
import lrdbench

# Generate synthetic data
from lrdbench import FBMModel
fbm = FBMModel(H=0.7, sigma=1.0)
data = fbm.generate(1000)

# Run comprehensive benchmark
from lrdbench import ComprehensiveBenchmark
benchmark = ComprehensiveBenchmark()
results = benchmark.run_comprehensive_benchmark()

# Get analytics summary
summary = lrdbench.get_analytics_summary()
print(summary)
```

### **Enhanced ML and Neural Network Estimators**

```python
# Import enhanced estimators directly
from lrdbench import CNNEstimator, LSTMEstimator, GRUEstimator, TransformerEstimator

# Use CNN estimator
cnn_estimator = CNNEstimator()
hurst_cnn = cnn_estimator.estimate(data)

# Use LSTM estimator
lstm_estimator = LSTMEstimator()
hurst_lstm = lstm_estimator.estimate(data)

# Use GRU estimator
gru_estimator = GRUEstimator()
hurst_gru = gru_estimator.estimate(data)

# Use Transformer estimator
transformer_estimator = TransformerEstimator()
hurst_transformer = transformer_estimator.estimate(data)
```

### **Simple Benchmark: Classical vs. ML**

```python
# Run focused benchmark comparing classical and ML estimators
from lrdbench import SimpleBenchmark

benchmark = SimpleBenchmark()
results = benchmark.run_benchmark()
analysis = benchmark.analyze_results(results)

# Results show ML estimators significantly outperform classical methods
print(f"ML MSE: {analysis['ml_mse']:.6f}")
print(f"Classical MSE: {analysis['classical_mse']:.6f}")
```

### **Advanced Usage**

```python
# Generate data with contamination
from lrdbench import FGNModel
from lrdbench.models.contamination.contamination_models import ContaminationModel

fgn = FGNModel(H=0.6, sigma=1.0)
clean_data = fgn.generate(1000)

# Add comprehensive contamination
contamination_model = ContaminationModel()
contaminated_data = contamination_model.add_noise_gaussian(clean_data, std=0.1)
contaminated_data = contamination_model.add_trend_linear(contaminated_data, slope=0.01)

# Run comprehensive benchmark with contamination analysis
results = benchmark.run_comprehensive_benchmark()
```
