I've used inferCNV to predict CNVs based on single cell expression data, and now I wish to calculate the "CNV score" as conducted in this publication.
It says: "The CNV score of each cell was calculated as quadratic sum of CNVregion"
The possible values are 0.5, 1.5, 2 - but what does "Quadratic sum" mean?
Is it sum of i^2 ? if so, isn't 0.5 is less represented vs 1.5?
