Just being curious... JASP vs jamovi

[dr_Primus]

So... Since jamovi is related to JASP.... I wanted to give JASP a go to see what are the differences... This are my (statistics layman) observations.

Everything is tested using MacBook Air (early 2015, i5 8G RAM, High Sierra)

1. jamovi has automatic updates.... very nice touch (who knows maybe JASP has them as well, but I just installed the most recent version)
2. jamovi has syntax mode and nicer GUI (I am a sucker for blue color)
3. jamovi doesn't require Xquartz to run (but it seems to me that it runs a little bit slower) - btw... how come that there are no jamovi menus in MacOS menu bar?
4. tables made in JASP are a bit nicer (less whitespace) when doing copy paste to MS Word, but on the other hand I can save jamovi tables as PDFs
5. jamovi's functionality can be extended with modules!
6. jamovi has motivated me to start learning R - I got my PhD degree two weeks ago, and statistics has become my hobby
7. jamovi has a phenomenal data editor, with row filtering and computed variables - this is the most important feature!!!


I have recommended jamovi to all my colleagues (most of them have pirated copies of SPSS or Graphpad Prism - I have tried a 30 day trial of Prism and IMHO it is too complicated to use and not worth the price with these wonderful open source alternatives).

Anyway... I am about to submit an article on CPR survival with two of my residents (sample of 1440 patients) and all the data analysis was made using jamovi - once the article is accepted I hope that more people will become interested in jamovi.

One more question... What happened between you guys and JASP guys... Why did jamovi fork from JASP?
I hope I am not being rude for asking such a question... I'm just being curious

haha, no worries. here's a couple of interviews that will fill you in:

this is an earlier one on the history of jasp:

Thanks

That was an interesting read

Hello any plans to implement this? The query here is from 7 yrs ago!!

Interesting read of the JASP vs Jamovi blog article there too. Years ago I started using JASP, but then I gravitated towards jamovi because in general I find it to be more stable, especially last 2 yrs or so it NEVER crashes (which is a credit to the developers) whereas I find that JASP still crashes even whilst doing rudimentary things like setting up a data table.... BUT JASP contains a few neat little features that jamovi does not incorporate yet eg: simple effects for rm ANOVAs and also the inclusion of effect sizes for post-hoc comparisons.

what are you referring to? what do you miss in jamovi?

[jonathon]

simple effects are just a different way of doing post-hocs? i.e. all the information for simple effects are available in post-hoc results?

To my understanding, simple main effects analysis is 'a priori' whereas post hoc is 'a posteriori'.

Hence a limitation of post-hoc analysis occurs for certain 2-way (or 3-way) research designs where many of the 'a posteriori' pairwise comparisons are irrelevant to the research question and therefore the correction for family wise error rate can be way too strict which thus leads to a increase in risk of type II error. A priori planned comparisons or simple effects analysis are more appropriate in these scenarios.

haha sorry damn I was checking a couple of old threads (one which was asking for implementation of simple effects analysis). Mistakenly, put this post in the wrong thread I guess
