Save your output file(s) under `/app/output`. Compute two covariance matrices from the Quantitative Risk Management dataset: the sample covariance matrix from daily percentage price changes (annualized by 252), and the efficient covariance matrix using the Ledoit-Wolf method. Save them as `sample_covariance_matrix.csv` and `efficient_covariance_matrix.csv`, following the format of `template.csv`. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
