## Scale factor

Specifies how to calculate the scale factor. You can choose between **Fixed**, **Constant** and **Varying over time**. If you select **Fixed** then you must specify a value for the scale factor in the space provided.

## Estimate constant term

Specifies whether to include a constant in the model.

## Quadratic estimation

Controls whether to use quadratic estimation for the data-based covariance/correlation matrix

## Form of correlation matrix

Lists different structures available for the covariance/correlation matrix over the times of the repeated measurements. If you select **Dependence** or **Ante-dependence** then you must specify the order of the covariance/correlation structures in the space provided. Also, if you select **Dependence** you must choose whether to specify that the correlation changes with the time of the repeated measurement using the check box provided.

## Available data

This lists data structures appropriate to the current input field (**Weights** or **Offset**). Double-click a name to copy it to the current input field or type the name.

## Offset

Specifies a variate that can be used to take account of a fixed contribution to the linear effects for each unit, referred to as the offset.

## Weights

A variate of weights can be supplied to give varying influence of each unit on the fit of the model.
