Credit LGD Model

WHENWhen implementing data acquisition for LGD regression model

ACTIONReturn a DataFrame containing exactly 'X' and 'Y' columns

CONSEQUENCEThe downstream lgdModel.py module accesses df[['X']] and df['Y'] columns without validation, causing KeyError exceptions if column names are different

WHENWhen implementing local file mode (choice=1) in dataSource

ACTIONRead CSV file from server_dirs/{server_id}/regression_data.csv path

CONSEQUENCEpandas.read_csv will raise FileNotFoundError if the file path is incorrect, and there is no try-except handler to provide meaningful error messages

WHENWhen configuring data transport for the LGD model

ACTIONPass choice values other than 1 or 2 to dataSource

CONSEQUENCEIf choice is neither 1 nor 2, the function returns None implicitly, causing lgdModel.py to fail when trying to access df[['X']] columns
