Hello, Here is last week's progress and this week's plan for `scipy.stats` improvements. *Week 5 topics:* - nan checks discussion. - Deprecation of `threshold` discussion. - `ppcc_max` - `fligner` and `bartlett` - `cumfreq` and `relfreq` *Mid-term evaluation week topics:* - Mid term evaluation: *submitted.* - nan checks initial PR. - 'alternative' keyword for `ansari` or `ks_2samp`. - Deprecation of `threshold` scheduled for this week. This week's main goal is to have a good idea of implementation details on the nan checks and 'alternative' keyword addition. Also to begin discussion on several other stats functions issues to have as many as possible to work on for the next two weeks or so that Ralf will be on break. For your reference: - Open Pull Requests <https://github.com/scipy/scipy/pulls/aeklant> - Open StatisticsCleanup issues <https://github.com/scipy/scipy/issues?q=is%3Aopen+is%3Aissue+milestone%3AStatisticsCleanup> Regards, Abraham.
