WebThis allows us to revise the above formulae fo rthe Mann-Kendall test as: s g n ( x i − x j) = { 1, x i − x j > ε 0, x i − x j ≤ ε − 1, x i − x j < − ε, and: Z M K = { E [ S] − 1 V A R ( S), E [ S] > ε 0, E [ S] ≤ ε E [ S] + 1 V A R ( S), E [ S] < − ε. These revised formulae are the ones that are implemented in the test () of this module. WebThe Mann–Kendall test (Mann 1945; Kendall1975) is calculated as Eq.(1) S = ∑ ∑ n sgn(x j −x i ) =i +1 −1 (1) Where n is the number of data points, x i and x j are the data values in the time series i and j ( j＞i ), respectively, and sgn(xj – xi) is the sign function, Eq.(2). − − = − = + − − = 1 0 0 0 1 0 sgn( ) i j i j i j j i
