After that projections of preprocessed data onto the first five PCA loading vectors are performed to obtain five new observations (scores).
Further, we have identified interaction and feedback mechanisms between diagnostic observations (scores) and decisions (criteria to treat) which implicate that errors are not independent.
Because no gold standard for metritis scoring and few validated criteria for metritis treatment exist at present, the accuracy of observations (scores) and classification (treatment or not) cannot be evaluated against a 'gold standard'.
If all three observers gave the sphere an observation score of 0 or two observers gave the sphere a score of 0 and the third observer gave it a score of 1, then the sphere was scored as "not observed".
If all three observers scored the sphere with an observation score of 2 or two observers scored the sphere with an observation score of 2 and the third observer scored it with a value of 1, then the sphere was scored as "observed".
This could have made the observation score more accurate.
The observation score did not include observation of the child by a psychologist.
A large number of families (79%) received a high mean observation score, a score between 4 and 5.
> Backward regression analysis also indicated a possible association between a lower age and a higher observation score value (β −0.253, p = 0.046).
Furthermore, a parent scoring high on the trait anxiety questionnaire was associated with a higher observation score (β 0.373, p = 0.005) but a lower heart rate SDS (β −0.395, p = 0.038).
