|
## Usage |
|
|
|
|
|
```python |
|
|
from datasets import load_dataset |
|
|
import pandas as pd |
|
|
|
|
|
# Load the dataset |
|
|
dataset = load_dataset("jab13/daily-statcast-data") |
|
|
df = dataset['train'].to_pandas() |
|
|
|
|
|
# Basic analysis |
|
|
print(f"Total pitches: {len(df):,}") |
|
|
print(f"Date range: {df['game_date'].min()} to {df['game_date'].max()}") |
|
|
|
|
|
# Pitch type distribution |
|
|
pitch_types = df['pitch_type'].value_counts() |
|
|
print("Most common pitch types:") |
|
|
print(pitch_types.head()) |
|
|
|
|
|
# Exit velocity analysis |
|
|
hits = df[df['launch_speed'].notna() & (df['launch_speed'] > 0)] |
|
|
print(f"Average exit velocity: {hits['launch_speed'].mean():.1f} mph") |
|
|
``` |
|
|
|
|
|
## Data Pipeline |
|
|
|
|
|
This dataset is maintained by an automated pipeline that: |
|
|
1. Fetches daily Statcast data using pybaseball |
|
|
2. Cleans and standardizes the data format |
|
|
3. Merges with existing data and removes duplicates |
|
|
4. Updates the Hugging Face dataset with new information |
|
|
|
|
|
## Data Quality |
|
|
|
|
|
- **Deduplication**: Removes duplicate pitches based on game_pk, at_bat_number, and pitch_number |
|
|
- **Standardization**: Consistent data types and null value handling |
|
|
- **Validation**: Ensures data integrity before upload |
|
|
|
|
|
## Updates |
|
|
|
|
|
The dataset is automatically updated daily at 6 AM UTC to include the previous day's games. Updates typically include: |
|
|
- All pitch-by-pitch data from completed games |
|
|
- Corrected data for any previously uploaded games |
|
|
- Advanced metrics and calculated fields |
|
