DunnettTest

[ShoumoBhattacharyaLab]

Please let me know if the DunnettTest implementation is one-tailed or two-tailed - I cannot find this in the documentation. Many thanks Shoumo

Hi Shoumo Thanks for using DescTools. The Dunnett test as it is implemented in DescTools only returns the two-sided p-values. I simply didn’t think of one-sided tests, when coding it. If you need one-sided tests you can make use of the package PMCMRplus, which also has a function dunnettTest() allowing to pass the known ‘alternative’ argument.

In future I might also include this in DescTools::DunnettTest()… 😉

Best, Andri

Hello Andri

I have a request - Dunnett test is parametric, is it possible to incorporate a similar but non-parametric test (one control - many comparisons, multiple testing correction) for data that is not normally distributed? Or is such a test already available in DescTools?

Best wishes

Shoumo

Hi Shoumo

I have no knowledge of such a test, sorry.

Best, Andri
