Re: Post hoc tests in Walrus (Robust ANOVA)

Oh. OK. So it looks like the other value of supp (i.e., "VC") is excluded completely from the interaction post-hoc test. So probably best to just remove the "interaction" post-hoc test table since, for whatever reason, it doesn't actually work right.

Re: Post hoc tests in Walrus (Robust ANOVA)

I would also have doubts. For example, in a Walrus (bootstrap) robust ANOVA on the Tooth Growth Data, I think there should be 15 post-hoc comparison. But the output produces only 3.

Re: Reorder output

I found a non-technical work-around: I simply include a 'table of contents' telling the reader wear to look in the numbered-but-out-of-order analyses. For example . . . RESULTS Contents Response Time General Descriptives for RT (#5) ANOVA of RT (#3) Rj planned comparisons for ANOVA of RT (#6) Accura...

Re: seolmatrix

What I've found is that many institutional computers have app blockers that may allow core aspects of jamovi to run while blocking other aspects. I've found that this blocking is especially likely to affect modules. Moreover, I've found seolmatrix to be more affected than any other jamovi module I u...

Re: Contigency tables

Oh. Sorry. However, I think those comparative measures are only computable in situation where the analysis can be conceptualized as comparing two things (to proportions, two ratios, etc.). Thus, they only work for 2 by 2 tables: https://cran.r-project.org/web/packages/chisquare/chisquare.pdf I've se...

Re: Contigency tables

Hi. jamovi's chi square contingency analyses aren't limited to 2 by 2. 3 by 4 works just fine.

Re: Jamovi to support Apple Silicon chips

@jonathan Is there supposed to be a jamovi Version 2.5.x for Windows, or is the new version only for non-Windows platforms?

Re: Comparing a mix of paired and unpaired data?

The quantified parameter needs to be a 'close-enough' approximation to interval/ratio. Most analysts think that the kind of scores you have are close enough. You can adjust for multiple comparisons. You'll need to use something like jamovi's Rj module (or R). See the example code, below: # This code...
