Hierarchical multiple regression involves deciding the order of entry for variables ahead of time, allowing researchers to control for certain variables by entering them first, and potentially reducing Type I error by limiting the number of steps in the variable entry process, thus controlling the inflation of error rates associated with multiple comparisons.
