- \({\text{CE}} = 1 - \sum\limits_{t = 1}^{n} {\left( {D_{{{\text{rec}}}} (t) - D_{{{\text{cal}}}} (t)} \right)^{2} } /\sum\limits_{t = 1}^{n} {\left( {D_{{{\text{rec}}}} (t) - \overline{D}_{{{\text{rec}}}} } \right)^{2} }\), where \(D_{{{\text{rec}}}} (t)\) and \(D_{{{\text{cal}}}} (t)\) denote the recorded and calculated displacement at time t, respectively; \(\overline{D}_{{{\text{rec}}}}\) is the mean recorded displacement, and n is the number of displacement records. The CE is used to measure the similarity between the calculated and observed displacements. A more accurate fit is obtained when the value of CE is approximately one
