**Time series analysis (TSA), **

### Definition of Time series analysis (TSA):

Trend forecasting (extrapolation) techniques (such as autoregression analysis, exponential smoothing, moving average) based on the assumption that the best estimate for tomorrow is the continuation of the yesterdays trend. TSA is more suitable for short-term projections and is used where (1) five to six years time series data is available and (2) where relationships between different values of a variable and their trend is clear and relatively stable. Instead of building a cause-and-effect (causal) model, TSA aims to isolate the sources of variations in a set of data so that their effect on a variable can be determined.
