x |
Can be either a data matrix or a covariance matrix |
missing |
How to handle missing values. |
standardize |
When TRUE Results are standardized by using the correlation matrix instead of the covariance matrix for computation. |
Lambda1 |
Guttman's Lambda1 estimate of reliability. |
Lambda2 |
Guttman's Lambda2 estimate of reliability. |
Lambda3 |
Guttman's Lambda3 estimate of reliability. Also known as Cronbach's alpha or coefficient alpha. |
Lambda4 |
Guttman's maximimal Lambda4 estimate of reliability. |
Lambda5 |
Guttman's Lambda5 estimate of reliability. |
Lambda6 |
Guttman's Lambda6 estimate of reliability. |
The estimate for Lambda4 is maximized.
