Analytic Methods

Chapter 14 Analytic Methods

This book has focused on computational methods like simulation and resampling, but some of the problems we solved have analytic solutions that can be much faster to compute.

🔗

This chapter presents some of these methods and explains how they work. At the end of the chapter, I make suggestions for integrating computational and analytic methods for data analysis.

    filename = basename(url)
    if not exists(filename):
        from urllib.request import urlretrieve

        local, _ = urlretrieve(url, filename)
        print("Downloaded " + local)
