Time Series Analysis used in uni variate and multivariate analysis. like uni variate models is ARIMA( Auto Regressive integrated Moving Average).This model is accurate forecasting for uni variate data set. next multivariate tool is VAR (Vector Auto Regressive). example: rainfall and rice production, gold prices for US Dollar and Indian Rupee ect..

time series analysis used to forecasting and future prediction for secondary time based data sets. not only time like year, month, hour, minutes ect...Basic test in time series analysis is regression. regression is one dependent and one independent variable. more independent variable available the data set used to multiple linear regression.
