Previous: Statistical Measures
Structural equation modeling requires independent
observations. Moreover, the mean as well as the variance contain
sampling error. Therefore, two independent estimates for
the mean were obtained, as well as two independent estimates for
the variance. The assumption was made that the sampling error of the
minimum reaction time could be neglected.
The following observed variables were used for EQS:
The following latent variables were used
The following equations were included in the model:
with the following constraints: all the variances of the error
components equal to each other and all covariances between the error
components equal to null.
