The quality index was calculated as a sum of grouped linearly normalized variables multiplied by group factor of significance and relatively to the CON bread.
Where model assumptions hold, the difference in mortality risk depending on episode is quantified by a sum of group risks.
The sum of group-specific estimates, and the estimate of total population size obtained by pooling data from all communities for analysis, appear at the bottom.
Those were also estimated by two-way ANOVA on normalized perfect match (PM) data of Affymetrix GeneChips, under the assumption that differences in PM data were the sum of group effects and probe sensitivity [ 22].
The sum of group and public activity contact-level-hours per-person-per-day is similar for 5th (172), 9 10th (182) and 11 12th (177) graders, with the dip in 7th (154) grade still present.
F i) is the BSS/WSS (between-groups sum of squares/within-groups sum of squares) ratio first used in [ 13] for multiclass molecular classification.
Recently, the concept of total health inequalities has been introduced, which is the sum of "between-group" and "within-group" inequalities; research has mainly focused on the "between-group" component [ 43], i.e. immigrants versus natives.
For any prime (p), there exists a finitely presented soluble group G with centre ((C_p)^{ infty )}), an infinite direct sum of cyclic groups of order (p) (see [103], as well as [104, Lemma 4.14]).
A discrete group A is pure projective in ℘ if and only if A is a direct sum of cyclic groups.
Hence, E is a direct sum of cyclic groups.
