If you are using Anaconda, then you can create a new environment and install the software. instead of downgrading scipy, it's better to upgrade statsmodels. Thanks for the prompt replies! In case it wasn't immediately obvious to anyone else, the workaround for this specific issue with missing function chisqprob is, Hello @avishaylivne is your problem fixed? However, there is a simple workaround by assigning the missing function back into the scipy.stats namespace as shown above, i.e. jinja2: 2.10 (/anaconda3/lib/python3.6/site-packages/jinja2) By.

Have a question about this project? Note this is in DiscreteResults so it will cause errors in all discrete models, i.e all summary will be "dead". How can I perform a likelihood ratio test on a linear mixed-effect model? This is the case for the macrodata dataset, which is a collection of US macroeconomic data rather than a dataset with a specific example in mind. @kennmyers , @josef-pkt Thanks for contributing an answer to Geographic Information Systems Stack Exchange!

We’ll occasionally send you account related emails. Restarting the kernel got me back to the original error, so I went and updated Anaconda, statsmodels and scipy, and now when running model.summary() I am again looking at a summary full of nan, and these errors which show up above and below the output: /anaconda3/lib/python3.6/site-packages/statsmodels/discrete/discrete_model.py:2127: RuntimeWarning: overflow encountered in exp Was this fixed in scipy version 1.0.0 If the issue has not been resolved, please file it in the issue tracker.

File - statsmodels\discrete\discrete_model.py @NaderNazemi This will not be fixed (reverted) in scipy (given also the existence of a simple workaround). @Abraham-Leventhal things you should try: If the code runs after performing steps 2 and/or 3, and you're still seeing all of the NaNs, there is probably something wrong with your model and/or data. Default is None, which means that no plot is created. Statsmodels is a Python module that allows users to explore data, estimate statistical models, and perform statistical tests.
