sienaModelOptions: Function to allow entry of model options

Description

Displays a Gui with model options, and allows editing of effects plus running of Siena07

None

Called from the Apply function in siena01Gui. An internal function of siena01Gui.

Various parameters can be set on the upper part of the screen:

Estimation Method: 0 for Unconditional fitting, 1 for Conditional. If there are multiple dependent variables, a list will be displayed from which to choose.
Standard starting value: If checked, the estimation will ignore the initial values of the parameters in the effects object, and use the default ones.
Specify random seed: If you wish your run to be repeatable, check this box and then choose any integer as the seed.
Number of processors: If checked, a box will appear for you to select the number of processors to be used. All processes will run on the same machine.
Initial value of gain parameter: A parameter to control the Robbins-Monro algorithm. Will be multiplied by the number of processors before use.
Number of phase 2 subphases: Default 4. To omit phase 2, set this to 0.
Derivative method: 0 for finite differences, 1 for score function. Default 1.
Number of phase 3 iterations: Default 1000.

If you wish to restrict the degree of the simulations, enter the value in the table on the bottom left.

Desired effects can be selected by using the botton Edit effects. Change the Include column to a 1 to select, 0 to deselect.

Initial values can be specified in the initialValues column.

If it is desired to fix a parameter, set the fix column to 1.

To request a test, set both the test and fix columns to 1 and specify the value against which to test in the initialValue column.

Some effects have parameter values: these can be specified in the parm column.

Check the included effects by using the Show included effects button.

The model can be fitted by using the Estimate button.

The data objects can be saved to an R data set using Save to file.

The results object can be saved to an R data set using Save results.

The Display Results button is a toggle and should display or remove the display of the results file.

Exit Model Options allows you to return to the previous screen.
