Cronbach's alpha method is also defined in
Bonett, D. G. and Wright, T. A. (2015) Cronbach's alpha reliability: Interval estimation, hypothesis testing, and sample size planning, J. Organiz. Behav., 36, pages 3– 15. doi: 10.1002/job.1960.
Describe the solution you'd like
prec_alpha
implementing functions 3 and 4 in the appendix. Maybe 2? Plus equivilents to get N given a CI width.
