what model do i get when calculating oxmetrics when calculating timeseries in oxmetrics does arima get errors how to compute arima in r r arima method how to find the timeseries using arima method how to find arima in r r arima method definition oxmetrics arima calculation what is arima if fitarma is used for r the coefficient change will be the same? is r arima used for timeseries oxmetrics temp model time series regression r error when using arima what is the result does oxmetrics use the constantterm how to estimate coefficients in r which package is used to use the arima model oxymetrics calculates what from arima why oxmetrics cannot calculate r models oxmetrics error
