# Analyse the risk of a business using Risky Business

## Functions :
1. Sharpe Ratio
2. Returns & Volatility
3. Risk by Return Ratio
4. Compounded Percentage
5. Annual Drawdown
6. Skewness & Kurtosis
7. Value Added Risk (VaR - Historic, Gaussian, Cornish-Fisher)
8. CVaR - Historic
9. VaR Comparison Plot

**Important** : Read the DOCUMENTATION section below before implementing any of the functions.

## Installation  

Use the package manager [pip](https://pip.pypa.io/en/stable/) to install riskybusiness

```bash
pip install riskybusiness
```

## Usage

```python
import riskybusiness as rb
rb.FunctionName(dataset = Your_Dataset)
```
> Make sure the dataset is loaded using pandas with the necessary columns.

A sample program using all the functions is displayed in risky.ipynb
 - Open using Jupyter NB or Google Colab
 - This file contains the output samples of all the functions present in the library.

! DOCUMENTATION !

# Welcome!
In order to use the RiskyBusiness library make sure you have installed it using :
```bash
pip install riskybusiness
```

To use the functions, Please import the library into your ipynb file using :
```python
import riskybusiness as rb
```

### Additional Libraries that need to be imported :
1) pandas
2) numpy
3) matplotlib.pyplot
4) from scipy.stats import norm

### Important :
1) Make sure the dataset is imported with pandas.
2) There are NaN values present (tip : use the dropna() function*)
3) Specify the required columns during/after import but BEFORE running the functions.
