Selects information to be printed by the generalized linear mixed model analysis and controls certain aspects of the method used.
Display
This specifies which items of output are to be produced by the analysis.
| Model | Details of the model that is fitted |
| Components | Estimates of variance parameters |
| Effects | Estimates of effects |
| Means | Tables of means |
| Back-transformed means | Tables of back-transformed means |
| Variance-covariance matrix | Variance-covariance matrix for the variance parameters |
| Monitoring | Monitoring information at each iteration |
| Wald tests | Wald tests for fixed model terms |
Dispersion parameter
Controls whether the dispersion parameter for the variance of the response is estimated from the residual mean square of the fitted model, or fixed at a given value. The dispersion parameter (fixed or estimated) is used when calculating standard errors and standardized residuals. In models with the binomial or Poisson distributions, the dispersion should be fixed at 1 unless a heterogeneity parameter is to be estimated.
Available data
This lists data structures appropriate to the current input field. The contents will change as you move from one field to the next. Double-click a name to copy it to the current input field or type the name.
Offset
A GLMM can be modified to take account of a fixed contribution to the linear effects for each unit, supplied in a variate referred to as the offset.
Factorial limit on fixed model terms
You can control the factorial limit on fixed model terms to be generated when you use model-formula operators like *. The default is to include all interactions, up to those involving nine variates or factors. (You cannot ask for more than nine.)
Model terms for means
This specifies the model terms, as a formula, for which tables of means and/or back-transformed means are displayed. If this field is left blank then all the fixed model terms are displayed.
Maximum number of iterations
Lets you specify the maximum number of iterations of the GLMM algorithm.
Standard errors
This specifies which standard errors are to be displayed with the tables of means.
| Differences | Summary of standard errors of differences between means |
| All differences | Full matrix of standard errors between means |
| Estimates | Summary of standard errors of differences between means |
| Variance-covariance | Variance-covariance matrix for the table |
Model options
| Estimate missing data values | Specifies whether predictions are formed from the fitted model for missing values of the y-variate; alternatively any units with missing values in the y values are excluded from the analysis. |
| Include units with missing factor values | This specifies whether data units with missing values in any of the factors in the fixed or random models are included in the analysis. |
| Estimate constant term | Specifies whether a constant term is included in the model |
| Covariates centred to zero weighted mean | Controls whether covariates are centred to have zero (weighted) mean for the analysis. |
Fitting method
Specifies the method used to form the fitted values. The option All specifies that both fixed and random terms should be used to form fitted values, which gives the method of Schall. The option Fixed indicates that only fixed terms are used to form fitted values which gives the marginal method of Breslow and Clayton.
