In coefficientalpha: Robust Coefficient Alpha and Omega with Missing and Non-Normal Data

Print alpha/omega and its confidence interval.

Description

Print alpha/omega and its confidence interval.

Usage

## S3 method for class 'alpha'
summary(object, type = "raw", prob = 0.95,...)
## S3 method for class 'omega'
summary(object, type = "raw", prob = 0.95,...)

Arguments

object	Results from the function alpha or omega.
type	If not raw, the CI based on transformation will be provided. The transformed CI will be always in the range of [0,1].
prob	Alpha level for confidence interval. By default, the 95
...	Option can be passed to the summary function.
