Auto-correlation of sequence travel residual — residual

residual_autocorrelation Calculates the average autocorrelations of the residual sequence of travel time.

residual_autocorrelation(data, network_parameters, lag = 1L, nsamples = 500L)

Arguments

data: A data frame of trips and their road level travel information, formatted as trips, see trips or data(trips); View(trips).
network_parameters: An output of link_mean_variance, see ?link_mean_variance.
lag: Maximum lag at which to calculate the autocorrelations. Default is 1 for the first order-autocorrelations.
nsamples: The number of trips to sample for parameter estimation. Default is 500.

Returns a data frame of lag order and autocorrelation estimates.

A residual sequence is a sequences of (duration_sec_i - E[duration_sec_i])/sd(duration_sec_i) for the i links of a trip.
