what type of series are non stationary var model non stationary does var show that demand series are non stationary which model is stationary demand can we test for non static rainfall in a VAR if it is static or nonstationary is the demand series non stationary which model is used to compare sales and demand based on rainfall how can i tell if var series are non stationary? why is rainfall a non stationary series which data sets are non-stationary is rainfall a stationary series var model is stationary or non stationary what is var model var model - how to predict rainfall is rainfall a stationary time series how to estimate rainfall using var when a model based on a nonstationary model is used is rainfall non stationary var models of time series is rainfall a stationary time series
