%description
Quantify the serial correlation across lags of a given functional time
series using the autocorrelation function and a partial autocorrelation
function for functional time series proposed in Mestre et al. (2021)
<doi:10.1016/j.csda.2020.107108>. The autocorrelation functions are based
on the L2 norm of the lagged covariance operators of the series. Functions
are available for estimating the distribution of the autocorrelation
functions under the assumption of strong functional white noise.
