Specify the manipulated variables and parameters for a Case Study

For each Case Study, you can manipulate up to two variables and parameters at a time in the following combinations:

• Two variables

• One variable and one parameter

• Two parameters

Each Case Study must include at least one manipulated variable or parameter.

You should specify only independent, specified variables as manipulated variables.

Specify the manipulated variables and parameters for a Case Study

1. On the Case Study Manager, select the Case Study, and then select Edit.

   The Case Study opens in the Case Study Editor.

2. In the Variables and Parameters area, in the Manipulated flag column, select the flag icon for the variables and parameters that you want to manipulate.

   

3. For each manipulated variable or parameter:

   1. In the Min column, enter the minimum value for the variable or parameter.

      This serves as the starting point for the variable or parameter and is the value in the first case of the Case Study.

   2. In the Max column, enter the maximum value for the variable or parameter.

      This serves as the endpoint for the variable or parameter and is the value in the last case of the Case Study.

   3. In the Steps column, enter the number of steps that you want the software to take to transition from the Min value to the Max value.

   The software automatically calculates the Size value, which is the change in the variable or parameter value for each step. You cannot change this value.

   

   You can enter Min, Max, and Steps values for observed variables. However, the software does not change the values for observed variables during a Case Study run.

   You should always set the Min, Max, and Steps values for a manipulated Integer parameter such that the Size value is a whole number. Otherwise, a warning appears for the Case Study and your cases likely won't solve.
