A correlation between B (the "before" value) and D (a before-after difference score that you compute).

Hi. This actually does not work in JASP 0.15.0 (Windows 10). It generates an error, as shown below. https://forum.cogsci.nl/uploads/723/8JBAWDSZJJX9.png

It's not so surprising to me. To what degree do your data meet all of the underlying assumptions? For example, nonlinear relationships between the predictors and the criterion variable could really screw things up. Obviously, the ideal way to identi…

Here's a relevant and recent in-press paper: https://sites.google.com/view/complexcognitionlab-bgsu/research/publications-references/lab-publications/biasing-the-input

My thought is, that would only make sense in a narrow range of circumstances. One circumstance is when there are just two levels of a factor being compared, in which case a directional t test could be used instead of an ANOVA. Another is when the de…
-
In any t test, the theoretical, sampling distribution of t scores is distributed according to a t distribution, not a normal distribution. It is the population(s) of raw scores, from which the data scores are sampled, that are assumed to be normally…

I believe that what you want to do is run an Analysis of Covariance, with two groups and one covariate.

The solution (without having to write code) was given to me some time ago in another thread: https://forum.cogsci.nl/discussion/4041/feature-request-allow-each-row-within-a-loop-to-run-different-sequence#latest Also, I've created a simple, working e…

https://forum.cogsci.nl/uploads/903/PQSDRP24D10G.jasp In the attached file, you can see that when an ANOVA is conducted on the raw Y data) along with Levene's test for variance inequality, Levene's test shows that the variance for Group A is signif…

FYI: My finalized slide. https://forum.cogsci.nl/uploads/169/0K4IXDAJ7M88.png
-
OK. My slide is getting really close. I hope it is permitted to speak of a "prior probability" distribution (even though the probabilities don't sum to 1.0), such that: "Prior to knowing the data, this is a distribution of the subjec…
-
OK. This is good. I'm now feeling more positive about increasing the emphasis I place on Bayesian statistical analysis in my classes and my research. Regarding my annotations: (1) Perhaps I can say "This distribution is NOT NEEDED for hypothes…
-
Yes you are welcomed to use it. But I guess it would be more accurate to use version below, which says that the null hypothesis is "not shown." http://forum.cogsci.nl/uploads/277/TFLJC3L76H8O.png
-
OK. Here's a slide that I could use for teaching: I've annotated the JASP output to indicate how its various components are to be interpreted. I would be grateful for any feedback concerning errors in the annotation. http://forum.cogsci.nl/uploads/…

However, that "posterior" distribution does not equal: ( 50:50 times ( P(D|"A zero-variance distribution located at ES = 0.0") / P(D|"A Cauchy distribution located at ES = 0.0 with scale = .707") ) ) That's because t…
-
Dear MSB, Thank you. I think you are right and that I was quite wrong. But what this as done is help me better conceptualize and describe what may now be stronger reasons to backslide. I think that my misconception stemmed from what might be seen as…
-
But the variances would not approximate normal distributions, which would be problematic for a t test. Wouldn't the most straight-forward, well-established way to do this be to simply run a repeated-measures ANOVA with Condition (with levels X, Y, a…
-
jploenneke Yes. Another way to put it is: Levene's test is just a oneway ANOVA on dispersion scores (absolute deviations from the group mean) that indirectly tests the equality of variance in the un-transformed scores. So a Bayesian one-factor ANOVA…
-
OK. Thanks! I now see how the RUN IF functionality, combined with sequence-within-a-sequence, can indeed randomly order the blocks/inner-sequences. So it's not necessary to implement the feature I requested. Perhaps adding a section on it, in the do…
-
And the tree representation would look like this: (Image)
-
Thanks. That solution had not occurred to me with regard to randomizing the order of different sequences (as opposed to randomly selecting which sequence(s) to run or not run). But suppose I have inner_sequence_1, inner_sequence_2, inner_sequence_…
-
I believe Vesna's question was about randomizing the order in which the blocks are presented (where each block includes its own loop of trials), not randomization within a loop of trials.
-
Arturo. I am also planning to try to use the Tobii T120 with OpenSesame. Did you get it working?
-
Thanks! that clarifies a things a lot for me. One more related question. For me, in the context of statistical analyses, I almost always to the prior model odds to be equal: p(H1) = p(H2). So am I correct to think that in this kind of (equal priors)…
-
FYI. I've installed the newest version, and it has fixed the Python crashes.
-
Thanks. Also FYI. The crashes, for me, happen with Windows 7. And I can't remember what version of 3.1 I was using before moving to 3.2. But when I go back to version 3.1.9 I still get python crashes--except that the crash occurs before the experime…
-
Also note that even in OpenSesame 3.1.9, about a third of the time when I try to run an OpenSesame, experiment, there's still an error in launching the experiment. But in this situation, the experiment is fine IF it launches. But about a third of th…
-
When I launch OpenSesame and it opens the default, 'new experiment': * If I change the runner to inprocess it runs without error (instead of resulting in a Python crash). * With the runner still set to inprocess: if I delete the welcome message, or…

Here's the entire contents of the debug window after I launch OpenSesame 3.2.1 and click the "Run Fullscreen" button. . . Python 2.7.13* Type "help()", "copyright()", "credits()" or "license()" for …
-
Thanks. It was not the backend (the backend was not different, and changing the backend in 3.2.1 doesn't avoid the Python 2.7 error). For now, I'm simply reverted back to OpenSesame 3.1.9, and everything is working fine again. [Re: Hi, These Pytho…
