# Bayesian Hypothesis Assessment
A Bayesian hypothesis assessment framework, tailored to comparing pairs of experiments. This package is preliminary
implementation statistical analyses described in [this paper](#citation). This can also be seen as a complimentary to
[testSignificanceNLP](https://github.com/rtmdrr/testSignificanceNLP) package which contains popular Frequentist tests.
We focus on the setup where the performances of two algorithms, applied on a certain dataset, are provided based on an
evaluation measure. The comparison is done by studying the posterior probabilities (rather than binary commonly-used binary decisions in other tests.)
For further discussion of the approaches implemented here (and their comparison to other techniques), refer to [the paper](#citation) or the extended [manual](docs/MANUAL.md).
## Getting started
### Installation
For running this code, you will need **Python (version >=3.6)**.
You have two options for installation:
- If you don't want to modify any code, you can just install the package and use it in commandline:
```bash
> pip install HyBayes
```
- Alternatively, if you'd like to make modifications to the code (e.g., the underlying model) you can clone this project. Before running the code, make sure that you have all the requirements by
running the following line to install all the necessary dependencies:
```bash
> pip install -r requirements.txt
```
In case you have issue with installing GraphViz, consider using conda installer:
```bash
> conda install -c anaconda graphviz --yes
```
If you are using MacOS, `brew` command can used:
```bash
> brew install graphviz
```
### Preparing configuration file
To analyze your data, you need to prepare the a configuration file that specifies the information needed for the analysis (e.g., the address to your observation files, the type of plots and files you want to be stored).
You can find more details on this in the [extended manual](docs/MANUAL.md#preparing-configuration-files). Additionally, there are examples of complete configurations in [`configs`](configs) folder, after running `make_configs.py`.
## Running the Analysis
Let's assume that you have followed the above instructions and:
- (1) you have included the performances observations in two separate files,
- (2) and you have prepared a config file.
To run the analysis, you pass the name of the config file as argument:
```bash
> python -m HyBayes --config my_config_file.ini --verbose
```
When the flag `--verbose` is on, the details of the analysis will be printed in standard output.
This flag does not affect the log file that is stored along side other outputs.
And here is the general usage template which can be accessed using `--help` flag at any time:
```bash
> python -m HyBayes --help
usage: __main__.py [-h] [-c CONFIG] [-v] [--make_configs] [--make_data]

optional arguments:
-h, --help show this help message and exit
-c CONFIG, --config CONFIG
address of Config file
-v, --verbose prints the report of the steps
--make_configs if on, example configuration files will be made.
--make_data if on, example data files will be made.
```
### Examples
To demonstrate everything with a quick example, run the following command to generate toy data:
```bash
> python -m HyBayes --make_data
```
You can see that some artificial data is made in directory `artificial_data`. Moreover either use the config files provided in the repository [], or run:
```bash
> python -m HyBayes --make_configs
```
And then execute the analysis on any of the newly made config files. For example:
```bash
> python -m HyBayes --config configs/config_metric.ini --verbose
```
