Let Y t be a time series that can be decomposed with the help of these four components: Secular trend T . Seasonal variations S . Cyclical fluctuations C .
Read moreWhich method is used for time series data analysis?
The exponential smoothing method is used to predict the short term predication. Alpha, Gamma, Phi, and Delta are the parameters that estimate the effect of the time series data. Alpha is used when seasonality is not present in data. Gamma is used when a series has a trend in data.
Read moreWhat is time series analysis algorithm?
Time series analysis is a method used for analysing time series data in order to extract meaningful statistical information from the data . Time series forecasting however, is all about predicting future values based on previously observed values over time.

Read moreIs a trend analysis the same as time series?
Time-dependent trends are a unique feature of time series analysis . If the sequence of events matters, then you need to analyze possible trends. These trends can ultimately be used for creating models that predict future values.
Read moreWhat do you mean by time series data give an example in data mining?
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. Examples of time series are heights of ocean tides, counts of sunspots, and the daily closing value of the Dow Jones Industrial Average.
