Methods of dealing with big data. Currently, each institute (center) uploads patients’ data to the NinJa database and the mean vector is computed using the aggregated data (a); however, the mean vector can be calculated based on mean vectors and sample numbers which computed in each center independently (b). In the future, mean vectors from various regions or countries (α, β, γ) will be aggregated and the mean vector of big data can be obtained (c)
