Getting Started

These instructions will help you get started with using the PySRAG package.

Prerequisites

Before you begin, ensure you have met the following requirements:

• Python 3 installed
• Required Python packages (you can install them using pip):
  • pandas==1.5.3
  • numpy==1.23.5
  • scikit-learn==1.2.2
  • lightgbm==4.0.0

Installation

You can install the PySRAG package using pip:

pip install PySRAG

Usage

Here's an example of how to use the SRAG package:

from pysrag.data import SRAG
from pysrag.model import GBMTrainer

# from https://opendatasus.saude.gov.br/dataset/srag-2021-a-2023
filepath = 'https://s3.sa-east-1.amazonaws.com/ckan.saude.gov.br/SRAG/2023/INFLUD23-16-10-2023.csv' 

# Initialize the SRAG class
srag = SRAG(filepath)

# Generate training data
X, y = srag.generate_training_data(lag=None, objective='multiclass')

# Train a Gradient Boosting Model
trainer = GBMTrainer(objective='multiclass', eval_metric='multi_logloss')
trainer.fit(X, y)

# Get Prevalences
trainer.model.predict_proba(X)
