Feedback for Group Assignment 2.4¶

CEGM1000 MUDE: Week 2.6, Friday, Nov 22nd, 2024.

Overall comments:¶

Most students showed basic programming skills and completed tasks with minor errors. Effort and understanding were evident in some parts, especially earlier sections.

Common Issues:¶

Frequent misuse or misunderstanding of linear detrending, often leading to excessive offsets or incorrect assumptions.
Many failed to correctly integrate AR(2) models, often defaulting to AR(1) or using non-stationary data.
Seasonal components were often implemented or interpreted incorrectly (e.g., missing key periodic signals or overfitting the model).
Data handling errors, such as using incorrect frequencies or failing to process offsets properly.
Mixing up mathematical components, e.g., cosine and sine terms, or incorrectly combining residuals and matrices.
