sounds reasonable to me. Stefan, you created those plugins. Do you agree, too? > btw, i also added support for tests against costants to the t-test plugin, > is that ok? This looks ok to me for the moment. I corrected a typo, and the initial value of the constant. However in the long run, there is a bunch more features that we should add: - Testing an arbitrary number of variables against each other or against a constant - Support for data in long format (single outcome variable and grouping factor). Using all levels or selected levels of the grouping factor(*). - Various modes of alpha correction I think having all of that inside a single plugin will be too much, so we will have to split all that into two or more plugins. Once at that point, I think it may make sense to restore one "very simple" t-test plugin, which may or may not look like the one without support for testing against constants. BTW, while testing your addition, I noted some more details that could be improved: - "Paired sample" and "Assume equal variances" should probably be on the same tab. Having mutually exclusive options on different tabs has some potential for confusion. - "Print confidence interval" should be a checkable frame, instead of a checkbox. Should I go ahead and do that, or are you still working on the plugin? Regards Thomas (*) And I know, that's another use case for a <valueselector>.
