figure 16-2 ebook version
figure 16-2 in ebook version: kindle location 21322
I implemented the author's python code in chapter 16, and was unable to accurately reproduce figure 16-2 exactly (I was able to reproduce figure 16-1 exactly). My blue lines are slightly different (a few percent) from the figure blue lines, but more importantly the red lines are significantly different in the upper half of the figure. The book figure (in my kindle version) shows what appear to be three red lines exactly overlapping blue lines in the upper part of the figure, which is apparently an error, given the stochastic nature of the lines. Also, one would expect a symmetric up/down dispersion of red lines, but they cluster towards the bottom of the book figure. I would be happy to submit my version of figure 16-2 at your request. I'm running mavericks on a macbook pro.
Note from the Author or Editor:
The figure is indeed not correct for multiple simulated paths -- the correct figure can be found in the IPython Notebooks hosted under http://oreilly.quant-platform.com or eg here (see output promt ):
