The function F i is a positive combination of sums and products of step functions s + and s − defined by s + x ¯ j, θ j k = 1, x ¯ j > θ j k 0, x ¯ j < θ j k, and s − x ¯ j, θ j k = 1 − s + x ¯ j, θ j k, and expresses the conditions under which species i is activated.
Here an example: "Competencies are the positive combination of knowledge, ability and willingness in the availability of the individual to cope successfully and responsibly with changing situations" (Weinert, 2001, p. 27).

A positive MELD/ICG-PDR combination was defined as a high MELD score (MELD score > 25) and a decreased ICG-PDR (ICG-PDR < 20%/min), while all other possible combinations were defined to be a negative combination (Table 5).> -wrap-foot> Positive combination: MELD >25 and ICG-PDR <20%/min.
Each positive combination was verified by colony PCR.
The rates leading to character combinations supporting a positive correlation (the combinations of gallinaceous/SΔNA and non-gallinaceous/full-length-NA) were subtracted from the rates leading to opposing character combinations (non-gallinaceous/SΔNA and gallinaceous/full-length-NA).
These combinations were termed as "positive combinations".
