Linear Mixed Models Save

Use this to save results from a REML analysis in Genstat data structures.

After selecting the appropriate boxes, type the identifiers of the data structures into the corresponding In: fields.

Fitted values	Variate	Fitted values from the analysis
Residuals	Variate	Residuals from the analysis
Residual deviance	Scalar	Residual deviance from fitting the full fixed model
Residual degrees of freedom	Scalar	Residual degrees of freedom after fitting the full fixed model
Predicted means	Table	Predicted means for the specified term
Variance matrix of means	Symmetric matrix	Variance-covariance matrix for the predicted means
Standard error of difference between means	Symmetric matrix	Standard errors of differences between the predicted means
Estimated effects	Table	Estimated regression coefficients for the specified term
Variance matrix of effects	Symmetric matrix	Variance-covariance matrix for the estimated effects
Standard error of difference between effects	Symmetric matrix	Standard errors of differences between the estimated parameters of each term
Akaike information coefficient (AIC)	Scalar	Akaike information coefficient to assess the random model
Schwarz information coefficient (SIC)	Scalar	Schwarz information coefficient to assess the random model
Unit variance-covariance matrix	Symmetric matrix	Matrix giving the fitted variance-covariance relationship between all the units. Note: this may be very large. This uses the random and residual terms, but not spline terms. It cannot be formed if the model contains sparse inverse covariance matrices.

Display in spreadsheet

Select this to display the results in a new spreadsheet window. The format of the table of Predicted means and Estimated effects is controlled by the Format drop down list.

Page format	Each table is displayed on a single page in a separate spreadsheet. The last specified classifying factor indexes the columns in the spreadsheet.
Column format	The tables occupy a single column but multiple tables can be put in a single spreadsheet. This is the default for a table with a single classifying factor.

Export to file

Save selected results into a Genstat or Excel file using the Save REML results in a spreadsheet dialog

Model terms for effects and means

Specifies the model term for which tables of estimated effects and predicted means are to be saved. The string ‘Constant‘ may be used to save results for the constant term. If tables of effects or means are required for more than one model term, this menu should be invoked once for each term, changing the specification of the model term each time.

Method for residuals

The list allows selection from type of residuals that can be calculated.

Combine all random terms	Use the residuals combined from all random terms.
Final random term only	Use the residuals from the final random term.
Standardized residuals from all random terms	Uses standardized residuals after combining them from all random terms.
Standardized residuals from final random term only	Uses standardized residuals from the final random term.
Combine all random terms, excluding spline terms	Use the residuals combined from all random terms except spline terms.
