Time Series Model: A Guide Built In

A time series is integrated of order d if $${\displaystyle (1-L)^{d}X_{t}\ }$$ is a stationary process, where $${\displaystyle L}$$ is the lag operator and $${\displaystyle 1-L}$$ is the first difference, i.e. $${\displaystyle (1-L)X_{t}=X_{t}-X_{t-1}=\Delta X.}$$ In other words, a process is integrated to order d if taking … Zobacz więcej In statistics, the order of integration, denoted I(d), of a time series is a summary statistic, which reports the minimum number of differences required to obtain a covariance-stationary series. Zobacz więcej An I(d) process can be constructed by summing an I(d − 1) process: • Suppose $${\displaystyle X_{t}}$$ is I(d − 1) • Now construct a series $${\displaystyle Z_{t}=\sum _{k=0}^{t}X_{k}}$$ • Show that Z is I(d) by observing its first-differences are I(d − 1): Zobacz więcej Witryna7 sie 2024 · Enter time series.
