quantiletools 0.1.0

Custom quantile calculation tools using Hyndman & Fan (1996) methods.

quantiletools

quantiletools is a Python package that implements the 9 quantile types defined in Hyndman & Fan (1996), with pure Python logic and no dependency on NumPy's np.quantile() methods.

🚀 Features

• Implements Types 1–9 from Hyndman & Fan (1996)
• No reliance on np.quantile(method=...)
• Dataset-level and group-level quantile summaries
• Fully vectorized for performance

📦 Installation

If downloaded locally:

pip install .

## 📚 Example Usage

```python
# Import from package 
from quantiletools import quantiles_for_vars, quantiles_by_group

# Example DataFrame
import pandas as pd
import numpy as np

df = pd.DataFrame({
    "X1": np.random.randn(10),
    "X2": np.random.randn(10),
    "Group": np.random.choice(["A", "B"], size=10)
})

# Compute quantiles
quantiles_for_vars(df, ["X1", "X2"], probs=[0.1, 0.5, 0.9], qtype=[1, 7])
