Reliability option: Omega / Alpha Ordinal

Discuss the jamovi platform, possible improvements, etc.

I like the reliability option but it would be great if, in addition to the regular alpha and omega, "ordinary" omega and alpha were included. Such reliabilities can be significantly attenuated for Likert style scales when the ordinal structure of the data is not taken into account. (It would be nice to add confidence intervals too)

I use the 'userfriendlyscience' R package for calculating my ordinal alpha and omegas (this package draws from the 'psych' package)

Thank you for listening to us
