Correlation matrix (Pearson r) of female preference (B and B′) estimates obtained from four different methodologies for the FQ trial of experiment 2 (n = 12)
| RRJ | Spline | Polynomial | |
|---|---|---|---|
| min2 | 0.35 | 0.91*** | 0.79*** |
| RRJ | 0.39 | 0.24 | |
| Spline | 0.93*** |
RRJ refers to the non-linear regression (Reinhold et al. 2002) and min2 refers to the application of the RRJ-method while excluding the phonotactic response of the two upper and lower extreme frequencies so that the preference estimates were derived from phonotactic response data that spanned 4–6 kHz
