The phrase "a sum of weights" is correct and usable in written English.
It can be used in contexts involving mathematics, statistics, or any situation where you are discussing the total of various weights combined.
Example: "To calculate the average, we first need to determine a sum of weights for all the items in the dataset."
Alternatives: "total of weights" or "aggregate of weights".
It follows from Lemma 2.1 in [3] that (v_{k}=c_{kk}) can be interpreted as a sum of weights of all directed spanning subtrees T of (mathcal{G}) that are rooted at vertex k.
The strength S i of a node i is a sum of weights of all connections of that node, i.e., S i = ∑ j w i j, where w i j is the weight of an undirected connection between nodes i and j.
Strength of metabolic connectivity was calculated for each VOI as a sum of weights of positive links (correlation coefficients) per VOI (Kaiser, 2011).
The energy efficiency was defined as the ratio of metabolic connection strength, a sum of weights of links connected to each VOI, to normalized FDG uptake of each VOI.
Then, the steady-state occupation probability of the node l in the network (graph) G becomes p l st = W l ∑ n W n, where the expression in the denominator obeys a summation over all sum of weights generated for the graph G to ensure that ∑ n p n st = 1.
Inpatient and outpatient data on diagnosis (ICD-10 codes) were used to measure the Charlson comorbidity index (CCI), which was defined as a sum of the weights related to each condition for which a patient had claims data available.
A 95% confidence set of selected models requires only the top three AICc best models, with a sum of Akaike weights of 0.995.
The score of a donor site (b-3,...,b6), where bj are nucleotides, was then calculated as a sum of positional weights: S b-3,...,b6) = W(b-3,-3)+...+W(b6,6), and S b-3,...,b6r scores of acceptor sites.
Let the score s(x) be defined as a sum of PO weights: (2) where b is a constant offset (bias), and we write x[i] k ≔ x i x i +1 … x i + k −1 to denote the substring of x that starts at position i and has length k.
Summary: CytoSaddleSum provides Cytoscape users with access to the functionality of SaddleSum, a functional enrichment tool based on sum-of-weight scores.
CytoSaddleSum is a Cytoscape (Smoot et al., 2011) plugin to access the functionality of SaddleSum, an enrichment analysis tool based on sum-of-weights-score (Stojmirović and Yu, 2010).
