GRM Introductory Overview - The Backward Stepwise Method

The backward stepwise method employs a combination of the procedures used in the forward entry and backward removal methods. At Step 1 the procedures for backward removal are performed. At any subsequent step where 2 or more effects have been selected for entry into the model, forward entry is performed if possible, and backward removal is performed if possible, until neither procedure can be performed and stepping is terminated. Stepping is also terminated if the maximum number of steps is reached.
