There are several types of MLR, including:

Type Characteristics
Direct (or Standard)
  • All IVs are entered simultaneously
Hierarchical
  • IVs are entered in steps, i.e., some before others
  • Interpret: R2 change, F change
Forward
  • The software enters IVs one by one until there are no more significant IVs to be entered
Backward
  • The software removes IVs one to one until there are no more non-significant IVs to removed
Stepwise
  • A combination of Forward and Backward MLR
