Quantify the smoothness of a vector
smoothness(x, method = "cor", lag = 1, iterations = NULL, ...)
Value of smoothness.
Numeric vector (similar to a time series).
Can be "diff" (the standard deviation of the standardized differences) or "cor" (default, lag-one autocorrelation).
"diff"
"cor"
An integer indicating which lag to use. If less than 1, will be interpreted as expressed in percentage of the length of the vector.
1
The number of bootstrap replicates for computing standard errors. If NULL (default), parametric standard errors are computed.
NULL
Arguments passed to or from other methods.
