Saddler

Data from a multiple baseline design conducted by 
Saddler, Behforooz, & Asaro, (2008). The variables are as follows:
<ul>
<li> <code>case</code> Student identifier 
 </li>
<li> <code>measure</code> Factor indicating the outcome measure (writing quality, T-unit length, number of constructions)
 </li>
<li> <code>outcome</code> Value of outcome measure.
 </li>
<li> <code>time</code>. Measurement occasion.
 </li>
<li> <code>treatment</code>. Factor indicating the treatment phase.
</li>
</ul>

datasets

Provides a set of tools for estimating hierarchical linear
models and effect sizes based on data from single-case designs.
Functions are provided for calculating standardized mean difference effect sizes that
are directly comparable to standardized mean differences estimated from between-subjects randomized experiments,
as described in Hedges, Pustejovsky, and Shadish (2012) <DOI:10.1002/jrsm.1052>;
Hedges, Pustejovsky, and Shadish (2013) <DOI:10.1002/jrsm.1086>; and
Pustejovsky, Hedges, and Shadish (2014) <DOI:10.3102/1076998614547577>.
