Initial Value Prior Information Pane

The Initial Value Prior Information pane is on the PEST Properties dialog box under Prior Information.

Prior information equations are described in the PEST User Manual, Part I, Section 4.15.

ModelMuse can automatically create prior information equations related to the the initial values of parameters. This pane is where the user can choose to include such prior information equations.

At the top of the pane is the Use initial value prior information checkbox. If the check box is checked, the initial values prior information equations will be included in the PEST control file.

The pane contains a table with four columns.

The Parameter Name column lists all the unfixed and untied parameters.

The Define Prior Information column specifies that the user wishes to specify a prior information equation for the parameter related to its initial value. In the case of parameters associated with pilot points, a prior information equation will be defined for each pilot point.

The Observation Group Name column specifies the observation group to which the user wishes to assign the prior information equations.

The Weight column species the weight that will be assigned to each of the prior information equations.
