Changed the shock scale parameter from 's' to 'ν' (Greek letter nu) to resolve the naming conflict with savings (s = x - c). This makes the code more readable and consistent with mathematical notation conventions. Changes: - Updated mathematical notation in text to use \nu instead of s - Changed Model NamedTuple field from 's' to 'ν' - Updated create_model function parameter from 's' to 'ν' - Modified shock calculation to use ν - Simplified Model instantiation to use positional arguments 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

This change improves code clarity by eliminating the confusing dual use of the variable 's'. Now 's' is used exclusively for savings (s = x - c), and 'ν' (nu) is used for the volatility parameter in the shock distribution. The Greek letter ν is a natural choice that aligns with common mathematical conventions for volatility parameters. |
