“Significance testing for variances in level 2 residual variance/covariance matrix G provides information about which level 1 slope coefficients are random. If the variance is not statistically significant you remove the random coefficient, …”

This is testing if you should have a random component for a level 1 variable. How do you do this in sas, that is where do you find the results (and is there a specific test you need to specify).
