Description
Dependent variables must be 0 or 1 values for binary regression.
Solution
If you want to use binary values that are not 0 and 1 values, you can map values to 0 and 1 using the dependent variable mapping parameter. This parameter allows you to map string values, such as yes and no to 1 (true value) and 0 (false value) values.
If you want to create your own mapping, you can create a field using Calculate Field to populate binary values based on criteria that you provide.
