Consider a data stream x1, ..., 35a, sampled from the independent Gaussian process X;~M0, 1)fori 0, 0 = 0, M; = maxlo, MM + (x,- - k)) for i > 0, U0 = 0 for the data stream x1, ..., gm The resulting stopping time 12;! sum is given as the first time period i, for which L,- CL (i.e., maxi-L5, M;) > CL). CL > 0 is a given "control limit\\f
