To me, AVE and alpha appear rather Mar 9, 2021 · A range of indicators, such as the average variance extracted (AVE), is commonly used to validate constructs. The average variance extracted has often been used to assess discriminant validity based on the following "rule of thumb": the positive square root of the AVE for each of the latent variables should be higher than the highest correlation with any other latent variable. 5, standardized factor loading of all CR values from 0. If we sum this by all variables, we get the sum of the variances (SS loadings) of all variables explained by a given factor. However, according to Fornell and Larcker ( 1981 ), even if AVE is less than 0. For models with multiple "blocks" (any combination of groups and levels), vectors may be returned as columns in a data. 2. AVE is calculated using the following formula ( Hair et al.
