Multilevel Models: Current Work<br />
• Applying multilevel models to these data allows <strong>for</strong><br />
different behavior patterns across cases, and can<br />
account <strong>for</strong> those differences using characteristics of<br />
the cases in the model.<br />
• We began analyses with a 1‐phase study (treatment<br />
only), then 2‐phase studies (AB), and are now<br />
working to model 4‐phase studies (ABAB).<br />
• At each stage, we’ve discovered new technical issues<br />
to be considered and accommodated.<br />
