Module suggestion: Corridors and points of stability

Everything related to the development of modules in jamovi

In my field of research (mostly social perception like attractiveness assessments and so on), we are always interested in how many raters do we need to have and how well they agree upon a given scale and stimuli. I am glad Jamovi provides some reliability measures like McDonald's Omega to tackle some of the "rating quality" measures.

However, some time ago I came across a concept of Corridors and points of stability (primarily for stability fo correlations) now extended to the stability of ratings, which I am trying to work in my data processing procedures.

See the following articles of what I mean:

Lakens, D., & Evers, E. R. K. (2014). Sailing From the Seas of Chaos Into the Corridor of Stability. Perspectives on Psychological Science, 9(3), 278–292.

Schönbrodt, F. D., & Perugini, M. (2013). At what sample size do correlations stabilize? Journal of Research in Personality, 47(5), 609–612.

Hehman, E., Xie, S., Ofosu, E., & Nespoli, G. (2018). Assessing the point at which averages are stable: A tool illustrated in the context of person perception. PsyArXiv Preprints.

Set of tests (estimating POS based on predefined COS) to assess "quality" of data would be very handy in jamovi.

I hope there is someone skilled in coding jamovi modules and might be interested in making one :-).
