PPT-Time-series analysis

Basic time series Data on the outcome of a variable or variables in different time periods are known as timeseries data Timeseries data are prevalent in finance and can be particularly challenging because.

A time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. . Hyun . Duk. Kim, . ChengXiang. (“Cheng”) . Zhai. (UIUC). Thomas A. . Rietz. (Univ. of Iowa) . Daniel . Diermeier. . (Northwestern Univ.) . . Meichun.
