Week 5: Introduction to multivariate autoregressive state-space models
Lecture topics:
The main lab is to go through case study 2 in the MARSS User Guide. I have a Fish 507 specific version of the case study code on the course website with questions to answer as you go through. Case study 3 and 8 are optional but going through them will help solidify your understanding of multivariate state-space models. Do go through the ARMA code as it discusses some important points about the effects of data transformation (in this case differences) on the time-series model that is appropriate for the data.

Week 5: Introduction to multivariate autoregressive state-space models
Lecture topics:
- Review of dealing with obs error with ARIMA (from last week)
- Multivariate state space models
- How these are expressed mathematically
- Analysis of multi-site data using this framework
- Parameter estimation: Kalman filter, Newton methods and EM algorithm
