The top portion of the resulting report shows the fitting of the Expected response. Description of Fit Statistics Report describes how the fit statistics are calculated. The Parameter Estimates and Fixed Effect Tests are similar to reports found in the standard least squares personality, though they are derived from restricted maximum likelihood (REML).

The second portion of the report shows the fit of the variance model. The Variance Parameter Estimates report shows the estimates and relevant statistics. Two hidden columns are provided:
The hidden column exp(Estimate) is the exponential of the estimate. So, if the factors are coded to have +1 and -1 values, then the +1 level for a factor would have the variance multiplied by the exp(Estimate) value and the -1 level would have the variance multiplied by the reciprocal of this column. To see a hidden column, right-click on the report and select the name of the column from the Columns menu that appears.
The hidden column labeled exp(2|Estimate|)is the ratio of the higher to the lower variance if the regressor has the range -1 to +1.
The report also shows the standard error, chi-square, p-value, and profile likelihood confidence limits of each estimate. The residual parameter is the overall estimate of the variance, given all other regressors are zero.
The Variance Effect Likelihood Ratio Tests refit the model without each term in turn to create the likelihood ratio tests. These are generally more trusted than Wald tests.
