Description
Hi EconML team, we're getting the below error in our builds:
Wondering if this logic should pass with empty arr in https://github.com/py-why/EconML/blob/479362aceb3205b6515adf5084f59a24ea79785d/econml/solutions/causal_analysis/_causal_analysis.py#L973
and if a new version of econml needs to be released so that our repo's builds can get unblocked with that - https://github.com/microsoft/responsible-ai-toolbox?
Thank you very much for your support!

Research direction
Start at econml/solutions/causal_analysis/_causal_analysis.py:973 and inspect the empty-array path associated with the reported ValueError. Reproduce the failure in the responsible-ai-toolbox build if possible, then determine the intended behavior for empty input and verify that the affected build is unblocked.
