研究方向
The issue requests a function to split a DataFrame into train and test sets. First, search the statsmodels codebase for existing train/test split utilities, such as in the sandbox/tools/cross validate.py file mentioned. Check if sklearn's train test split can be used as a dependency or if a similar implementation is planned. Look at recent comments for any maintainer guidance on whether this feature is desired or has been addressed elsewhere.
