Regression and Other Stories - Extra code

Additional code versions

R + Tidyverse version by Bill Behrman
R + brms + tidyverse version by Solomon A. Kurz (work in progress)
Python + Bambi version by Ravin Kumar, Tomás Capretto, and Osvaldo Martin (work in progress)

Source: extra.Rmd.

The Python version keeps data handling explicit and uses lapylace for Stan-backed generalized linear models, so the statistical model can be read from a formula rather than from handwritten Stan.

from pathlib import Path
import sys
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import lapylace as lp

sys.path.append(str(Path.cwd().parent / 'python'))
from data import ros_path

Notes

Source computation blocks represented: 0.
Data paths are expressed through the shared ros_path() helper.
Formula-based Bayesian regressions are routed through lapylace.stan_glm().
Plotting and simulation work uses NumPy, pandas, matplotlib idioms.
