WebApr 26, 2024 · Univariate time series: Only one variable is varying over time. For example, data collected from a sensor measuring the temperature of a room every second. Therefore, each second, you will only have a one-dimensional value, which is the temperature. Multivariate time series: Multiple variables are varying over time. WebOne difficulty is that the CCF is affected by the time series structure of the x -variable and any “in common” trends the x and y series may have over time. One strategy for dealing with this difficulty is called “pre-whitening.” …
