Correlations between boar sperm kinematic variables (unrotated solution) and latent factors (PF1, PF2) *.
| Variable | PF1 | PF2 |
|---|---|---|
| LIN | 0.99 | |
| STR | 0.92 | |
| WOB | 0.89 | |
| VSL | 0.75 | 0.60 |
| VCL | 0.98 | |
| ALH | 0.91 | |
| VAP | 0.86 | |
| BCF | ||
| Var Exp (%) | 53.1 | 44.9 |
Var Exp: variance explained in each PF. Total variance explained: 98.0%. * Expresses the more important variables in each PF. Only eigenvectors >0.6 are presented. VCL: curvilinear velocity; VSL: straight-line velocity; VAP: average path velocity; LIN: linearity of forward progression; STR: straightness; WOB: wobble; ALH: amplitude of lateral head displacement; BCF: beat-cross frequency. Bold is recommended for the appreciation of the total variance explained.
