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.
