Plotting the time varying model coefficients for regression models (eg. in MMM)

[rjscout24]

In the paper it is mentioned that the model coefficients are time varying. How do we plot this or get this data? I did not see any example code for this. I did see codes for regression but that just provided single values - are these calculated based on mean across all time steps?

There is a method available after you've fitted the model called "get_regression_coefs"
