1 What is a Time Series. A set of observed values ordered in time, or we can say, repeated measurement of something usually with the same fixed interval of time (hourly, weekly, monthly). A collection of observations made sequentially in time [ 1].

I am familiar with how to calculate the autocovariance functions of an AR (2) model, but I am not sure how I to go about calculating the autocovariance and partial autocorrelation functions of an AR (2) model such as Xt = aXt−2 +et X t = a X t − 2 + e t where |a| < 1 | a | < 1. Not that here we are missing the Xt−1 X t − 1 term.Lần trước, chúng ta đã biết cách ước tính xu hướng của bất kỳ chuỗi thời gian nào cùng với các thuộc tính thống kê có ý nghĩa như độ không chệch và phương sai.Lần này, bây giờ chúng ta sẽ tiến hành xây dựng các ước tính thống kê vững chắc về ACVF và ACF.
