The absurdity of multiple categories for literature is perhaps best illustrated by the case of James Baldwin, whose novel "Giovanni's Room" is about two gay white men in Paris.
Although the calculation of potential impact fractions would have permitted the use of multiple categories and not just binary high and low exposure with these variables, 52 the method assumes linearity, which we observed to not be the case.
Weighted versions of the Kappa coefficient exist for the case of multiple, ordered categories [24], [25], but interpretation is clouded further by an often arbitrary choice of weights for each category.
In the case of multiple exposure categories, non-differential misclassification may lead to an over-estimation of the risk parameters, especially when it occurs among non-contiguous exposure categories (Dosemeci et al., 1990; Birkett 1992; Wacholder 1995) Jurek et al. (2005) conducted a simulation study that indicated bias towards the null cannot be assumed.

Future research will be focused on the identification of dominant and most discriminative texture patterns for different motor fault categories and application of the proposed system in the case of multiple motor fault diagnosis.
We treated these categories following the above mentioned hierarchical order and the highest category was considered in case of seeking care from multiple categories of health care providers (for example if a baby sought care from unqualified providers on the first attempt and later sought care from a qualified provider, this baby was counted as a care seeker from a qualified provider).
The third category (type III in Additional file 2, Figure S6, which corresponds to the case of multiple homoplastic or overlapping inversion events on a single branch) is expected to be rare.
No cases of multiple parasitism were found.
Assignment of genes to multiple categories was tolerated.
