Reliability and Validity Measures

qualmeasures.Rd

A variety of reliability and validity measures.

Usage

qualmeasures(object)

Arguments

object

An object of class. This can be created via the gesca.run function.

Details

Cronbach's alpha and Dillon-Goldstein's rho (or the composite reliability) can be used for checking internal consistency of indicators for each latent variable. The average variance extracted (AVE) can be used to examine the convergent validity of a latent variable. The number of eigenvalues greater than one per block of indicators can be used to check uni-dimensionality of the indicators.

Value

Numeric vectors of the reliability and validity measures.

# Model specification

    # Measurement model
    OP =~ cei1 + cei2 + cei3
    OI =~ ma1 + ma2 + ma3
    AC_J =~ orgcmt1 + orgcmt2 + orgcmt3
