### Summary and key findings
- Application: A hidden Markov model of the term structure to modeling the Brazilian swap rate curve.
- Main empirical findings:
  - Two regimes are identified: a high level and a high volatility regime and a low level and low volatility regime.
  - Both regimes are persistent.
  - Regime dynamics are explained by the level and the slope of the term structure.
- Purpose: Examine the model's characteristics and its performance in describing the cross-sectional and time-series dynamics of the term structure.

### Model specification and methodology
- Model class: Hidden Markov model applied to the term structure (affine regime, ATSM).
- State dynamics: Markov chain / Markov-switching models governing regime transitions.
- Drivers emphasized: level, slope, mean reversion, volatility regime, market price considerations.
- Estimation approach:
  - Bayesian MCMC algorithm.
  - Produces consistent standard errors.
  - Provides a reliable method for testing the differences between the model parameters.
