"its" is written as "it's" multiple times throughout the book, e.g. "distribution of it’s Markov Process" on pg. 194

Thanks!

This is the first draft of the book, so we haven't done any general editing passes yet. We might not fix individual issues until we do a dedicated pass over the whole book and/or work with a professional editor. If it takes a while to fix this it's because we're batching the editing work together, not because we're ignoring your suggestion :).
