A closing parenthesis } is missing, but I'm not entirely sure what it is supposed to be so instead of making a PR I'm reporting this.

Thanks for reporting. I will take a look at it.

The bracket is missing for the upper bound in the final sum :) Feel free to open a PR for this!

\[d_t = \frac{\sum_{n=1}^{\text{N}} n (c_{t+n} - c_{t-n})}{2 \sum_{n=1}^{\text{N}} n^2} \]

It's unbalanced curly bracket. Will be fixed in #788.
