alphaci

Calculate confidence intervals for alpha and standardized alpha using asymptotic theory or the studentized bootstrap, with or without transformations. Supports the asymptotic distribution-free method of Maydeu-Olivares, et al. (2007) doi:10.1037/1082-989X.12.2.157, the pseudo-elliptical method of Yuan & Bentler (2002) doi:10.1007/BF02294845, and the normal method of van Zyl et al. (1999) doi:10.1007/BF02296146, for both coefficient alpha and standardized alpha.
