Simulation study conditions.

$ϵ$	Type I Error	Max Type I Error	Power (1)	Power (2)
$0.1$	$b_3^{\ast }$ = 0.08	$b_3^{\ast }$ = 0.02021	$b_3^{\ast }$ = 0	$b_3^{\ast }$ = 0.01
$0.3$	$b_3^{\ast }$ = 0.2	$b_3^{\ast }$ = 0.06290	$b_3^{\ast }$ = 0	$b_3^{\ast }$ = 0.03

Note: ε represents the equivalence bounds [recall that the equivalence interval is (−ε, ε)], $b_3^{\ast }$ represents the unstandardized interaction regression coefficient (which has an associated ${\beta }_3^{\ast }$ coefficient), and Max Type I error represents the case where the standardized interaction coefficient is on the edge of the equivalence interval (i.e. ${\beta }_3^{\ast }$ = ε). Power (1) and Power (2) represent two different conditions in which ${\beta }_3^{\ast }$ falls within the equivalence interval. Each case of $b_3^{\ast }$ represents a distinct condition, so there are eight different conditions. Note that each condition was repeated for each of the sample size conditions.
