WebIn R, the sample CCF is defined as the set of sample correlations between x t + h and y t for h = 0, ±1, ±2, ±3, and so on. A negative value for h is a correlation between the x -variable at a time before t and the y -variable … Web‘matrix’ ‘Date’ Time-based indices. xts objects get their power from the index attribute that holds the time dimension. One major difference between xts and most other time series objects in R is the ability to use any one of various classes that are used to represent time. Whether POSIXct, Date, or some other class, xts will convert this into an internal form to …
