Resolved: Where can I find explanation of the practical formula for price elasticity? I didn't find it in the notes and failed to do it by myself.

Hi Макс,  you can find the derivation for the formula in the course notes. They are in the lecture "Segmentation, Targeting, Positioning", under the quiz. Here is a link: https://learn.365datascience.com/courses/customer-analytics-in-python/segmentation-targeting-positioning   Best,  Eli

Hi Макс,  the formula derivations are in a separate pdf, which you can download here: https://learn.365datascience.com/courses/customer-analytics-in-python/calculating-price-elasticity-of-purchase-probability Sorry for the misunderstanding!   Best,  Eli    

i cant find the derivation of the formula, im verry interested
