[Gretl-users] Question on "meantest" command

Hi all, I have a question on the meantest command: https://gretl.sourceforge.net/gretl-help/cmdref.html#meantest It's not clear to me whether this command refers to the version for paired or unpaired samples. Here is some more background information: https://www.itl.nist.gov/div898/software/dataplot/refman1/auxillar/t_test... I've programmed the t-test for paired samples, for which the code can be found here: https://gist.githubusercontent.com/atecon/f1864d66ce76c45b783ec2839360dd5... This replicates what is named as "Program 3" on the nist-page (search for the expression "Example of paired t-test from p. 178 of Bowker and Lieberman") Given that the meantest command returns a different test statistics and p-value, I assume the meantest covers the unpaired sample case. If so, this should be mentioned in the help. Also, do you think it's worth to create a package out of my code? Let me add another point. Currently, we have the following packages: - Friedman.gfn - KruskalWallis.gfn Just for completeness, apart from the meantest command, there is also the difftest command: https://gretl.sourceforge.net/gretl-help/cmdref.html#difftest All variations are general tests on central tendency (I haven't found a more common or more general term for this). Here is a nice illustration of some existing tests (in German though): https://www.methodenberatung.uzh.ch/de/datenanalyse_spss/unterschiede/zen... Having a common "access point" may be useful as the current state is somehow confusing. What do you guys think about a new package combining at least the user-contributed packages "Friedman", "KruskalWallis" and optionally my test for the paired t-test? Best Artur
