Rather than focus on her pleasure, or whether her sexual desires are being fulfilled, she seems more concerned with receiving external validation of her attractiveness, thus reinforcing the idea that what women really seek is to be sexually desired by men: screw (no pun intended) actually having sexual desires of their own.
These findings need to be confirmed with a further study on a wider population belonging to more herds, and with external validation with an independent and representative set of test objects, in order to give relevant and reliable estimates on the prediction ability of the predictive models.
External validation is more relevant when a new risk score is proposed and its generalizability is of interest (1).
While the external validation requires more hospitals participating [ 9], studies in the future should examine it with larger sample sizes.
For example, although PLS ranked consistently near the bottom in the internal validation, it showed a steady decrease in accuracy rank in the external validation as more pathways are added to the classifiers, yielding a medium average rank of 3.3.
Although external validation is more difficult as it requires data collected from similar patients in a different setting or a different center, it is always preferred to internal validation.
Still by maintaining accuracy in differing patient populations, we believe PATHFx is sufficiently robust, and DCA suggests it may be used clinically, while undergoing additional external validation in more diverse patient populations.
Note that here we assume that the case mix of the validation study is identical to the development study; if this is not the case then the interpretation of the value of D (or, indeed, any other model performance measure) at external validation is more complex [ 29, 30].
