RTaxometrics #891

Open sujitiiml opened 4 years ago

sujitiiml commented 4 years ago

Kindly consider including the RTaxometrics package in JASP.

It is the standalone package developed by John Ruscio for conducting psychometric analysis and is widely published in well-reputed journals. Further, taxometric analysis is an essential part of a psychometricians toolkit, enabling us to determine whether the underlying latent structure of a construct is Categorical or Dimensional.

JorisGoosen commented 4 years ago

To add a package to JASP would not be sufficient for using it as an analysis I'm afraid. A form describing the options and an R-function that can handle these values is also necessary.

Have you used RTaxometrics?

Because in that case it might be interesting to set up such an analysis yourself, perhaps?

I think this is a request to implement the functionality of this package as a JASP module. We've discussed the possibility of adding IRT models before, but never got around to it. We are about to implement a bunch of modules, so let's keep this option in reserve until we have more time.

...or until many users start to ask for it :-)

Then count a second vote... for when you have more time :-)

I did not use taxometric analysis, probably like many of those who use JASP. But also neither Bayesian analysis nor network analysis, and yet their appearance in JASP was a breath of fresh air that enriched scientific research in psychology.
Taxometric analysis broadens the vision and understanding of latent constructs (so dear to psychologists). As much as I've seen, RTaxometrics should be easy to implement (basically, it has only 5 functions, the rest being automatically called by them).

Here, a tutorial that can be useful even to those who will try RTaxometrics outside JASP: https://pdfs.semanticscholar.org/5707/0cf69a68f60d3774e92470329d5f8ca2774a.pdf

Best regards, Marian

We can leave this open @sujitiiml then someone can pick this up at some point

sujitiiml commented 4 years ago

Sure @JorisGoosen

I'm glad to see someone has requested RTaxometrics be added to JASP. John Ruscio has created a pretty user-friendly R package, but having RTaxometrics in JASP would be a great feature to add in.

As well, as mentioned, considering adding in IRT or other mixture modelling approaches (like Latent Profile/Class Analysis) would be fantastic.
