We selected the top five according to three criteria: usefulness of information, ease of use and appearance (see table).Tops is Nouriel Roubini's website.
Eckman et al. (1990) classified intrinsic criteria used for making garment purchase decisions into aesthetic criteria, usefulness criteria, and performance and quality with extrinsic criteria.
However, the understandable system-generated questions are weakly correlated with the criterion of usefulness (r = 0.31), whereas for human-generated questions the correlation between the criteria understandability and usefulness is higher (r = 0.57).
It therefore integrates conventional criteria of validity with non-scientific criteria of usefulness.
We define several criteria (power, usefulness, flexibility, modularity, and, reliability) and investigate the properties of behavior sets using them.
However, as the designation to this type is based on a mixture of natural and technical criteria, its usefulness is limited.
However, the number of generated rules is generally very high and must be filtered according to user-defined criteria and usefulness measures.
As minimum criteria for usefulness for our studies we only chose tumor tissues in which tumor cells occupied a major component (> 80%) of the tumor sample.
Assessing formal statistical criteria and usefulness of the models, a 4-class solution best fitted the data: after switching medication two response groups with severe symptoms at study start and subsequent substantial treatment effects, and two showing no or comparatively little treatment effect, one of which had severe and the other less severe symptoms at study start.
It more closely matches the criteria for usefulness than other candidate biomarkers such as C-reactive protein, which is rather a nonspecific marker of acute phase inflammation, and proinflammatory cytokines such as plasma IL-6 levels that are highly variable, cumbersome to measure, and lack specificity for systemic infection.
