The two-sided standardized scale, i.e. standard deviation cusums will have its upper cusum value equal to ___________

\(S_i^+=max⁡\left\{0,v_i+k-S_{i-1}^+\right\}\)

\(S_i^+=max⁡⁡\left\{0,v_i-k+S_{i-1}^+\right\}\)

\(S_i^+=max⁡\left\{0,v_i+k-S_{i-1}^+\right\}\)

\(S_i^+=max⁡\left\{0,v_i-k-S_{i-1}^-\right\}\)

\(S_i^+=max⁡\left\{0,v_i-k+S_{i-1}^-\right\}\)
