The aim has been to give balanced representation of cases that are, and are not, favourable to planted forests; and of cases where approaches deliver a useful result, and those where results may be misleading.
Samples were selected from the GOG collection to balance patient age distribution, date of serum collection, and representation of cases and controls across collection sites.
The retrieval of relevant cases is directly linked to the data representation of cases and the applied similarity measure that evaluates the usefulness of cases regarding the current problem.
Using the pattern-based representation of cases described in the subsection Pattern space (above), we also carried out 100 two-means clustering experiments within the set of negative observations.
For Harrell's C, this bias arises because of the over-representation of case-case pairs, which are less likely to be concordant than case control pairs.
Adaptations for case-cohort data deal with the over-representation of cases compared to the original cohort design.
Therefore, there might be some under-representation of cases of infectious conjunctivitis in which no treatment was given.
This over-representation of cases with a homozygous GSTT1 deletion suggests that the GSTT1 enzyme plays an important role in glutathione conjugation of exogenous and/or endogenous substrates.
a Linear regression models were corrected for over-representation of cases and adjusted for maternal age, BMI, parity, centre, education, occupation and urine sampling conditions.
d Results corrected for over-representation of cases according to Richardson et al. (2007) and standardized for sampling conditions (excluding creatinine) using formula (1) in the methods section.
