The Parameters Page allows you to define and view the parameters of your model. Parameters are variables that can be referenced in formulas throughout your model. Each parameter has the following properties:
The name by which the parameter can be referenced in formula. Names are case sensitive, must start with a letter, contain only letters numbers and underscores, and may have a maximum of 20 characters. Note: changing a variable name will not change any existing references to this variable in formulas, these references will need to be changed independently.
|Description||A brief description of the parameter. May have maximum of 50 characters.|
|Category||The category of that this parameter falls under (e.g. Efficacy, Cost, etc.). Parameters can be grouped by category using the 'View' menu.|
|Formula||A short R-expression which determines the value of the parameter. Formulas are always edited using the formula bar.|
|Source||A brief description of the source of the parameter. Any URLs contained within the source will be automatically formatted as hyperlinks.|
You may find descriptions of additional functionality available on this page, and other similarly structured pages, here.
