Recently I wrote about the STATS CONVERT PYTHON extension command that converts Python 2 code to Python 3 so that you can use it with Statistics 27, which does not support Python 2 out of the box.  I wrote about this on the IBM Community site here

https://community.ibm.com/community/user/datascience/viewdocument/python-2-to-python-3-conversion-for-1?CommunityKey=886b6874-0fb1-402c-8243-c70ef8179a99&tab=librarydocuments

This command is now on the Extension Hub and can be installed via the Extensions > Extension Hub menu in Statistics 27.

Commands in the title of this post is plural, so I want to report that there is another new command also on the Extension Hub: STATS RESIDUAL BOXPLOTS.  This command can be useful in checking for heteroscedasticity and functional form problems in regression.  It produces a set of linked boxplots of residuals against predicted values.  Like most extensions, it has a custom dialog box and SPSS-style syntax.  When you install it, a short article on usage is saved in the STATS_RESIDUAL_BOXPLOTS directory under the installation location.

The command requires the appropriate version of R and the R Essentials for Statistics.  While it was developed using Statistics V27, I expect that it will work with V24 and later.
