terms |
β1
|
Slope or trajectory of the outcome variable
(appropriately drug use) until the introduction of peer
supervision. |
β2
|
Change in the level of appropriately drug use that
occurs in the period immediately following the introduction of peer
supervision. |
β3
|
Difference between pre-peer supervision and
post-peer supervision slopes of the Outcome |
β4
|
Difference in the level between intervention and
comparison prior to peer supervision |
β5
|
Difference in the slope between intervention and
comparison prior to peer supervision |
β6
|
Difference in level between intervention and
comparison in the period immediately following introduction of peer
supervision |
β7
|
Difference between intervention and comparison in
the slope after initiation of peer supervision compared with before peer
supervision being introduced. |
εt
|
Error term at time t representing unexplained
random variability in the model |
