what is the appropriate aic range of arima models when aic is approximately equal why do we use arima model when the aic is low what is the difference between a minimum aic and an approximately equal model? why is the option to have a model that just happened to give the minimum aic not a default in much of the time series forecasting software? what to do when the aic is equal what to do when the aic is low when aic is approximately equal to zero, what should i do when aima model is low what is aic? what to do when aic is approximately equal what to do when aic is approximately equal when aic value is low, what is done with aima which model should i look for when the aic is low? what is the minimum aic of arima what to do when the AIC is low? what is aima model what to do in an approximately equal time series model what to do if aic is approximately equal what to do if the aic is low
