Q & K Model

The Q3 & K1 Model tab is shown below:

A different Q&K Model tab is generated for each combination of Q and K matrices. Each of these tabs contains one each of the following elements for each trait variable:

•

One Model Fitting Information table

This table shows the values of model information criteria for a specific combination of Q and K matrices. These values are displayed on the Model Fitting Information plot alongside with other combinations of Q and K matrices and they can be used to compare and identify better fitting models to the current data

•

One Fixed Effects table

This table shows the parameter estimates of all fixed effects present in a specific model. Fixed effects include the intercept, the Q matrix variables, and any additional Fixed Threshold that might have been entered in the Model Variables tab of the process dialog.

•

One Random Effects table

This table shows the BLUPs estimates of all random effects present in a specific model. Random effects include the K matrix variables, and any additional Random Effects that might have been entered in the Model Variables tab of the process dialog.

•

One Covariance Parameters table

This table shows the covariance parameter estimates of all random effects present in a specific model. Random effects include the residual variance, the variance attributed to the K matrix, and the variance of any additional Random Effects that might have been entered in the Model Variables tab of the process dialog.
