[x] In “A stochastic matrix (or Markov matrix) is an 𝑛×𝑛 square matrix 𝑃 such that each row of 𝑃 is a probability mass function over 𝑛 outcomes.” delete “over 𝑛 outcomes”.
[x] Change titles “32.2.2.1. Example 1” and “32.2.2.2. Example 2” into titles that are intuitive of the respective examples.
[x] Express the matrix below as a table?
[x] For Example 3 (the example for democracy (D), autocracy (A), and an intermediate state called anocracy (N)), implement the following order: table; figure; matrix.
[TABLE]
[FIGURE]
[MATRIX]
[x] Change date to time in section of “32.2.3. Defining Markov chains”
[x] Add “(probability mass function)” such that “𝑃(𝑥,⋅) is the conditional distribution (probability mass function) of 𝑋𝑡+1 given.”
[x] In “It can be shown that for a long series drawn from P, the fraction of the sample that takes value 0 will be about 0.25.”, change to “It can be proven that for a long series drawn from P, the fraction of the sample that takes value 0 will be about 0.25.”
[x] In the section “32.4. Distributions over time”, have subsections dividing into two parts: “One unit of time” and “m steps in the future”
[x] In 32.4.1, move the function above (after “m-th power of 𝑃”). After the function, add text “For one way to see it, consider again (32.6), but now with a 𝜓𝑡 that puts all probability on state 𝑥.
[x] Then 𝜓𝑡 is a vector with 1 in position 𝑥 and zero elsewhere.
[x] Inserting this into (32.6), we see that, conditional on 𝑋𝑡=𝑥, the distribution of 𝑋𝑡+𝑚 is the 𝑥-th row of 𝑃𝑚.”
[x] In 32.4.2, instead of the link “considered above”, include the section number (32.4.1) with a link.
[ ] In 32.4.3, in (2), put a note to better explain “cross-sectional frequencies”. Maybe jump to the example rather than include the text after the two-numbered list?
[x] Search for “considered above” and replace it with section number and make sure the hyperlink works. (In pdf version, the “considered above” link does not work.)
