Hi Allen, Strange. I'll ask one of the experts on the team about this. Cheers, E.J.
-
Hi MIcheleS, Is your covariate the baseline score? If the covariate is not something you are interested in evaluating (but it is something you feel is important to include in the model) then you might just as well add it to the null model. The r sca…

Hi maalicious, We hope to add more support for survey analyses in the future. As far as the analysis goes, what analysis is meaningful depends on what question you seek to answer. Cheers, E.J.
-
Interesting question, I'll forward this to our expert. One would hope that a little more information would indeed be available. Cheers, E.J.

Hi Bianca, I'll tell our network expert to add some information to the help file (which pops up when you press the blue "i" icon). The help file does refer to paper like this one: Epskamp, S., Cramer, A. O., Waldorp, L. J., Schmittmann, V.…

Hi Tabea, It may be that you are using the default correction for multiplicity, and this does not assign equal prior probability to each of the models. In the table, the "best" model is the one with the highest posterior plausibility, and …

Hi Jorge, I'll forward this to our experts. Cheers, E.J.

Hi RadHead5, Hmm I will ask some other team members for their input. We do have linear mixed model functionality in JASP, but that does not produce Bayes factors at the moment. However, the Bayesian AN(C)OVA as implemented through the BayesFactor pa…

Hmm this is really not my domain -- I just know of the papers that critiqued the idea. I'd do some Google'ing and feel free to report the results of your search here! Cheers, E.J.

Hi Tom, That is really strange and almost seems more like a bug. I'll attend the team to this but you could also post this issue on our GitHub page (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/) Cheers, E.J.

I think you basically do a power analysis using the maximum likelihood estimator as the parameter value under H1, with the same planned sample size you actually had in the experiment. I don't think you can do this in JASP (because I would have put m…

Hi Raquel, This project is still marinating...I will put the pressure. If you post this as a feature request on our GitHub page, the people working on it will see it too. Cheers, E.J.
-
Hi Per, I will ask the team. Also, if you have any specific suggestions please let us know (maybe best to do this on our GitHub page, so the team won't forget!) Cheers, E.J.
-
I assume this is because the test is based on a pooled standard error, but I'll ask our expert to confirm this... Cheers, E.J.
-
Hi JT, When you say you want the "amount", I assume you'd like to standardized measure of effect size? -- because you could of course just report the cell means. I am generally a bit cautious about interactions that do not cross, because …
-
What was your t-value and what are the sample sizes? And what was your prior? E.J.

Reporting post hoc power is a terrible idea, as the number is just a transformation of the p-value. You can quote me on that. For a critique see Hoenig, J. M. and Heisey, D. M. (2001). The abuse of power: The pervasive fallacy of power calculations …
-
I think this issue has come up before, let me ask the team...
-
You probably intended to post this on a different forum. This is the place to discuss the interpretation of statistical results from JASP. Cheers, E.J.

Hello Tong, Almost correct -- the interpretation of the BF is that the data are about (1/0.272) time more likely under H0 than under the model with only cue_type. For examples see https://link.springer.com/article/10.3758/s13423-017-1323-7 https://w…

I do not immediately see how a quadratic contrast would be set up to find a U but not an inverted U. You could try generating data according to an inverted U (or take U-shaped data and transform it to give an inverted U shape), apply the software, a…

Early June. E.J.

Hi Per, This is why the Library allows you to click the csv icon (to the right of the JASP icon), which just gives the raw data without any analysis or annotation. Or is this not what you mean? If you have a feature request, it is best to use our Gi…
-
We don't produce the path diagrams. That certainly would be very nice to add. Cheers, E.J.
-
Correct E.J.

"Am I right to say that the cond model is the best model and adding presence into the model weakens it?" Yes. Second, "my concern here is whether I should be comparing cond + presence model with presence model (as per what I wrote in…
-
Yes, the same scale applies. Cheers, E.J.

Hi Tali, I am not aware of it, but I would advise you to check out our GitHub page (and, if you can't find it, post the issue there). Cheers, E.J.

Hmm I am not 100% sure what you would like. I assume that with "delta value" you mean the posterior point estimate of effect size? If so, see my earlier response. If not, could you clarify? Cheers, E.J.
