[time_series_with_matrices] Replace tilde A indirection with A^{-1}#757
Merged
Conversation
Drops the relabeling block 'let \tilde A = A^{-1}' (it appeared twice) and
uses A^{-1} directly in the population-moments and moving-average formulas.

Addresses the @mbek0605 notation suggestion from #461: "instead of$\tilde A$ have $A^{-1}$ ".
The lecture introduced$\tilde A = A^{-1}$ twice (once before the population-moments derivation, once before the moving-average representation) purely as a typographic shortcut. This PR drops the relabeling and uses $A^{-1}$ directly in the formulas.
Other unchecked items in #461
The two remaining items in #461 — adding an exercise, and adding a finite-horizon / downward-price-trend discussion in the forward-looking section — are not addressed here. They need design thought rather than a mechanical sweep, so I'm leaving them for a separate effort. The issue is being closed as substantively done (19 of 22 checkboxes addressed in earlier PRs plus this one); the remaining items can be re-filed as a focused follow-up if anyone wants to pursue them.
