# Relazioni
Relazioni is a lightweight package for strength of the relationship between variables analysis.

Documentation: https://chicodelarosa.com/relazioni \
Source code: https://github.com/chicodelarosa/relazioni \
Bug reports: https://github.com/chicodelarosa/relazioni/issues

It provides easy to use functions for measuring the relationship between variables of the following natures:

### Two Continuous
A variable that can reasonably take on any value within a range. Examples of continuous variables include height, weight, exam scores, income, salary, etc.

### Two Categorical
A variable that is a category without a natural order. Examples of categorical variables are eye color, city of residence, type of dog, etc.

### At least One Ordinal
A variable with categories that have an inherent order. For instance, education level (GDE/Bachelors/Masters/PhD), income level (if grouped into high/medium/low) etc.

### One Binary and One Continuous
A variable that is a category with only two possible values. Examples of binary variables include gender (male/female) or any True/False or Yes/No variable.

Relazioni currently supports 8 different association functions for investigating the relationship between variables in the following cases:

1. Two Continuous and Covariates
   * Partial Correlation (R)
2. Two Continuous and No Covariates
   * Pearson Correlation
3. Two Categorical and Two Values per Variable
   * Phi Coefficient
4. Two Categorical and More than Two Values per Variable
   * Cramer’s V
   * Theil's U
5. At Least One Ordinal
   * Kendall’s Tau
   * Spearman’s Rho
6. One Continuous and One Binary
   * Point-biserial Correlation

## Requirements
    scipy
    numpy
    pandas
    scikit-learn

## Installation
### Installing via pip
    pip install .

### Installing via setup.py
    python setup.py install

### Installing via Git
    python -m pip install git+https://github.com/chicodelarosa/relazioni.git

## Example
    import numpy as np
    from relationships import associations
    
    v1, v2 = np.array([1, 1, 2]), np.array([1, 1, 2])

    matth_corr = associations.matthews_corr(v1, v2)
    print(matth_corr) # 1.0

    v1, v2 = np.array([1, 1, 2]), np.array([2, 1, 2])

    matth_corr = associations.matthews_corr(v1, v2)
    print(matth_corr) # 0.5
