Thanks a lot for your excellent content!

Just wanted to highlight a potential issue in the code in chapter 19. In the code below, I think you mixed m1 and m2 in the assign method. It makes the interpretation of the results presented in the chapter quite confusing.

prices_rnd_pred = prices_rnd.assign(**{
    "m1_pred": m2.predict(prices_rnd[X]), ## predictive model
    "m2_pred": predict_elast(m1, prices_rnd), ## elasticity model
    "m3_pred": np.random.uniform(size=prices_rnd.shape[0]), ## random model
})

This code is located just before the section Elasticity by Model Band¶

Oh boy. You are right, thanks!
