One interpretation of the statistical complexity is that it is the minimum amount of historical information required to make optimal forecasts of bits in \(x\) at the error rate \(h_\mu\).

For periodic sequences, \(C_\mu(x) = 0\) and for ideal random sequences \(C_\mu(x) = 0\) too.

Several researchers have tried to capture the properties of statistical complexity with practical alternatives. The resulting complexity metrics include:
