Given our limited sample size, we wanted to assess development within age-appropriate groups but were not able to create smaller age groupings (i.e., 1-year groupings).
In the study, kappa values fall into three groupings: (i) a value greater than 0.80 (80%) represents strong agreement, ii) a value between 0.40 and 0.80 (40%to80%0%) represents moderate agreement, and (iii) a value below 0.40 (40%) represents poor agreement (Congalton 1991).
To concentrate our analysis on Italy and Portugal, the other countries are clustered into country groupings (i.e., regional blocks).
A lexicographical rank ordering of schools within each specific grouping would then be performed with greater emphasis given to attractiveness scores calculated from closer contextual groupings (i.e. through an alphabetical or dictionary style of sorting).
The inclusive nature of TribeMCL is attributable to its use of sequence similarity scores alone to assign groupings (i.e., this method is intended to identify homologs, in contrast to KOG and OrthoMCL, which purport to identify orthologs only).
This analysis was carried out separately for three regional groupings: (i) divisions within the PRH; (ii) area Te2 and the LEC; and (iii) the various cortical layers of the LEC.
