[Bug]: multipletests import fails in receptive_field.py

Start at line 37 of allensdk/brain_observatory/receptive_field_analysis/receptive_field.py and compare the failing statsmodels import with the location of multipletests described in the issue. Re-run the reported receptive_field import with statsmodels 0.15.0; done means the module imports successfully without the ImportError.

Describe the bug

receptive_field.py, L37

With statsmodels>=0.15.0, receptive_field.py fails to import multipletests from statsmodels.sandbox.stats.multicomp.

multipletests has been technically importable from sandbox.stats.multicomp for many versions (at least since some version 0.4.x). This is because in sandbox.stats.multicomp, multipletests was imported it globally from statsmodels.stats.multitest. In version 0.15.0, the global import was removed. As a result, the import in the allensdk's receptive_field.py now fails.

To reproduce

With statsmodels>=0.15.0 installed:

from allensdk.brain_observatory.receptive_field_analysis import receptive_field

Expected behavior

Import successful.

Actual behavior

Solution

The function should be imported as:

from statsmodels.stats.multitest import multipletests

That is where it is defined in the current version of statsmodels. And as noted above, as far as I can tell, that is where it has been since one of the 0.4.x versions from 14 years ago. So, I would not expect any backward compatibility problems.

The earliest version I was able to install in my environment was statsmodels==0.13.5 (from around 4 years ago?), and the import worked.

Environment

• OS and version: Ubuntu 24.04.4 LTS
• Python version: 3.11
• AllenSDK version: 2.16.2
• Install method (pip/conda/source): pip
• Execution context (local/CI/notebook/cluster): local
• Any pinned dependencies or unusual environment details: Statsmodels version 0.15.0

Are you willing to submit a fix?

• Yes, I can work on a PR for this
• No, but I can help test a proposed fix
