Installation

The easiest way to install pyconsensus is using pip:

$ pip install pyconsensus

Usage

To use pyconsensus, import the Oracle class:

from pyconsensus import Oracle

# Example report matrix:
#   - each row represents a reporter
#   - each column represents an event in a prediction market
my_reports = [[ 0.2,  0.7,  -1,  -1 ],
              [ 0.3,  0.5,  -1,  -1 ],
              [ 0.1,  0.7,  -1,  -1 ],
              [ 0.5,  0.7,   1,  -1 ],
              [ 0.1,  0.2,   1,   1 ],
              [ 0.1,  0.2,   1,   1 ]]
my_event_bounds = [
    {"scaled": True, "min": 0.1, "max": 0.5},
    {"scaled": True, "min": 0.2, "max": 0.7},
    {"scaled": False, "min": -1, "max": 1},
    {"scaled": False, "min": -1, "max": 1},
]

oracle = Oracle(reports=my_reports, event_bounds=my_event_bounds)
oracle.consensus()
