Taxon Base Rate Estimates for the Averaged MAXEIG and MAMBAC Curves for Each Indicator Set
| Indicator Seta | Procedure | Research Data | Comparison Data
|
|
|---|---|---|---|---|
| Taxonic | Dimensional | |||
| R8 | MAXEIG | .30 | .27 | .22 |
| R8 | MAMBAC | .21 | .22 | .20 |
| R5 | MAXEIG | .26 | .24 | .17 |
| R5 | MAMBAC | .23 | .19 | .17 |
| Q5 | MAXEIG | .24 | .24 | .26 |
| Q5 | MAMBAC | .41 | .34 | .36 |
| QR8 | MAXEIG | .25 | .28 | .19 |
| QR8 | MAMBAC | .32 | .31 | .29 |
| QR5 | MAXEIG | .24 | .24 | .18 |
| QR5 | MAMBAC | .30 | .29 | .29 |
| Mean | .28 | .26 | .23 | |
Note: MAXEIG = maximum eigenvalue; MAMBAC = mean above minus below a cut. Taxon base rate estimates calculated using the averaged curve for each taxometric procedure and indicator set, along with the mean of these estimates calculated across all samples of taxonic and dimensional comparison data. The bottom row is calculated as the mean across all 10 indicator set and taxometric procedure combinations. Within each row, the mean for the type of comparison data closer to the corresponding mean for the research data appears in boldface (this was assessed prior to rounding values for the table).
R = clinical rating data; Q = questionnaire data; QR = combined questionnaire and rating data; the abbreviation is followed by the number of indicators.
