• Hi Chuan-Peng, I've responded on github, see https://github.com/jasp-stats/jasp-issues/issues/1652#issuecomment-1067802157 Hopefully this clarifies it. Cheers, Alexander

  in R code for the "Bayesian Multinomial Test" implemented in JASP Comment by AlexanderLy March 2022
• Hi Richard, Thanks for reporting this. I've got the same error on mac, so it's safe to assume that it's not platform dependent. I've reported this bug on github see https://github.com/jasp-stats/jasp-issues/issues/1430 There you can find the jasp …

• Hi PeteE, Thanks for reporting this. The scatter plot at the top visualises the ranks of the two variables. This was done to help better visualise ordinal data for which the face values of the raw data are meaningless. Ideally, the scatter plot of …

• Hi Max, You can add interactions by going to the Model section and select multiple components with shift or ctrl and add them to the model terms simultaneously. Here's the gif for ANOVA, but the same principle holds for ANCOVA. https://jasp-stats.o…

  in Continuous and binary predictor Comment by AlexanderLy August 2021
• Hi agata_, The error message is not informative, as it implies that the Bayes factor could not be computed due to possibly a data error or an overflow. We should improve this. If possible, could you please open an issue with the jasp file on our gi…

  in Bayesian correlation - betaA note Comment by AlexanderLy February 2021
• Hi JW, It depends on how you set this up. If you do a linear regression with a categorical variable with values 0, 1, 2, then it's treated as a continuous covariate. If you'd like to test whether a categorical variable is relevant, then we recommend…

  in Linear Regression Reference Group Comment by AlexanderLy June 2020
• Hi Eric, One way to do this in jasp is via the compute column functionality and the filter. You can compute a new column by pressing the "+" symbol on the right hand side of the data view. After you ticked "+" you have to enter:…

  in Select Cases in JASP Comment by AlexanderLy March 2020
• Hi Eric, The builder requires a logical expression in the "test" argument. Here's an example: https://forum.cogsci.nl/uploads/673/C3DSVY165HC5.png In this example, I want a column consisting of 0s and 1s. If Happiness < 4, then it need…

• Hi Heiko, Could you please send me the jasp file [firstLetter].{lastName}@jasp-stats.org with a description of what you'd like to do to which variable? Then I can respond more tangibly. Cheers, Alexander

  in Recoding nominal variables into dummy variables Comment by AlexanderLy October 2019
• Dear Thalia,  To perform a Bayesian linear regression with nominal predictors we recommend using a Bayesian ANCOVA. Most likely you’re interested in the effects table. The effects table provides the evidence for the inclusion of a predictor across m…

  in Bayesian regression analysis using JASP Comment by AlexanderLy July 2019
• Hi Bob, Thanks for the question. We’re working on the interface to make row manipulations in JASP more intuitive. To do what you’d like in the current version of JASP, we have to resort to the R interface in compute column. The R code is then  appl…

  in Applying a function across variables in JASP Comment by AlexanderLy May 2019
• I'll see if we can get a 32bits flatpak version. I'll ask my wizard to free up some time.

  in Binomial test fail - beginner's question Comment by AlexanderLy October 2018
• There's no 32bits version of our flatpak build at the moment.

  in Binomial test fail - beginner's question Comment by AlexanderLy October 2018
• Hi normanp, It seems that you're running an 32bits version. We don't have a flatpak version for that. Instead, could you build JASP from source? The instructions are given here https://github.com/jasp-stats/jasp-desktop/blob/development/Docs/devel…

  in Binomial test fail - beginner's question Comment by AlexanderLy October 2018
• I don't think that that's necessary, though, I do think that that's good practice in general.

  in Binomial test fail - beginner's question Comment by AlexanderLy October 2018
• Hi normanp, Could you please try our flatpak build? https://jasp-stats.org/linux-installation-guide/ Let me know how that works out for you. Cheers, Alexander

  in Binomial test fail - beginner's question Comment by AlexanderLy October 2018
• Hi Anna, Thanks for your encouraging words. Can you please let me know which part of my comment was particular hard to parse? Then I'll be able to explain it better next it comes up. Thanks, Alexander

  in Bayesian one-sided independent samples t-test: question about the sequential analysis plot Comment by AlexanderLy August 2018
• Hi Eniseg2, Thanks for this report. There's nothing wrong with your data and your intuition is spot on. The first 9 Bayes factors are 1, and this is correct. The 11th Bayes factor and onwards are also correct. So there's no need to worry about thos…

  in Bayesian one-sided independent samples t-test: question about the sequential analysis plot Comment by AlexanderLy August 2018
• Hi Kasia, My approach was via the likelihood of the raw data in relation to the parameters, which I believe is something different from calculating a statistic and entering into a test, because the transformations you do to the data are not necessa…

  in Bayes Factor for single case - control comparison Comment by AlexanderLy November 2017
• Hi Kasia, The default Bayes factor based on the Cauchy distribution on the population effect size is set up in such a way that it returns one, whenever the data are uninformative and data sets with one of the group sizes less than two are considere…

• Glad to help! You can double click the data panel to access and edit the data set If it's not present it'll generate a data file for you Alternatively, here's the data file: Cheers, Alexander

  in How does JASP handle missing values exactly ? Comment by AlexanderLy November 2017
• Hi Curious1, "Exclude cases analysis by analysis" is basically the equivalent of "exclude pairwise" and "exclude listwise" is the same as before. Here's the JASP file explaining what happens in the paired t-test (what …

  in How does JASP handle missing values exactly ? Comment by AlexanderLy November 2017
• Sorry about that, both varE and varF should only have the fifth case removed. I was a bit too enthusiastic removing cases and I can't remove files once they have been uploaded. Please only consider exampleMissingCorrect.jasp

  in How does JASP handle missing values exactly ? Comment by AlexanderLy November 2017
• Hi Curious1, Here's a JASP file explaining the difference. Please let me know, whether it's clear. Cheers, Alexander

  in How does JASP handle missing values exactly ? Comment by AlexanderLy November 2017
• Hi GerineL, Updating your analysis If you update your data set you can tell JASP to rerun your analysis with the new data set. The steps to do this is to: - Go to file - Sync data - Current Alternatively, * you can use the short cut "ctrl-Y…
