how is a var model used how to predict a time series in a var model what is vector autoregressive modeling how can you implement an autoregressive model? how does a var model perform why would you use a var model which model uses only the lagged values of the other time series? how to use auto regression model what is var model used for when do i use a vari is time series of interest a vector how to improve forecast performance of time series? why var models are used how to forecast using vector autoregressive model how to use var to determine the lag values in time series what is the benefit of a var model when all of the time series contain information? how many model are there for forecasting how to make a time series more efficient how to use a tar modeling in forecasting what is the aver model of time series
