eda-report 1.4.0b0

A simple program to get a basic EDA report in .docx format.

Automated Exploratory Data Analysis

A Python program to help automate the EDA process.

Data is analysed using pandas' built-in methods, and graphs are plotted using matplotlib & seaborn. The results are then nicely packaged as a .docx file using python-docx.

Installation

You can install the package from PyPI using:

pip install eda-report

Basic Usage

1. Graphical User Interface

The eda_report command launches a graphical window to help select and analyse a csv/excel file:

eda_report

You will be prompted to set a report title, graph color and output filename, after which the contents of the input file will be analysed, and the results will be saved in .docx format.

2. Interactive Mode

You can obtain a summary for a single feature (univariate) using the Variable class:

>>> from eda_report.univariate import Variable
>>> x = Variable(data=range(50), name='1 to 50')
>>> x
            Overview
            ========
Name: 1 to 50,
Type: numeric,
Unique Values: 50 -> {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, [...],
Missing Values: None

>>> x.show_graphs()

You can obtain statistics for a set of features (multivariate) using the MultiVariable class:

>>> from eda_report.multivariate import MultiVariable
>>> # Get a dataset
>>> import seaborn as sns
>>> data = sns.load_dataset('iris')
>>> X = MultiVariable(data)
