Table 3. Percent Variance Explanation1 for Models Relating Facility Characteristics with Payment, Cost, and Net Payment, for Acute and Long-Term Psychiatric Episodes.
Characteristic | Payment | Cost | Net Payment |
---|---|---|---|
Teaching | 20.0 | 0.0 | 0.1 |
Psychiatric Beds | 0.1 | 0.9 | 1.1 |
RAM Group | 0.1 | 0.4 | 0.6 |
Variance explanation is the analysis of variance Eta-squared statistic for categorical variables (teaching and the resource allocation methodology [RAM] group), otherwise it is the R-squared statistic of a linear regression.
Not significant (p = .220); all others are significant at the p < .0001 level.
