Choose a parametric model
Given lifelines offers a variety of parametric models, you want to find the best model for the heart patients DataFrame heart_patients.
Use the AIC score to assess the fit of each model below:
- The Weibull model:
WeibullFitter - The Exponential model:
ExponentialFitter - The Log Normal mode:
LogNormalFitter
All lifelines fitters above have been imported for you. The pandas and numpy libraries are imported as pd and np, respectively. Use the console to explore the DataFrame and its column names as needed.
