why fit a r(1) model can you use the ara model for non stationary data who fit a static model for a government which term structure is used in government if a model is not stationary? what model is used in the government term structure why fit a r model which model can be based on non-stationary data? who used arc models what type of data are used for the ar model which data set can a r model be used? when to use arc data why is an arc model allowed in certain situations? why fit a r model on non stationary data why is an arc model necessary what data do researchers use for a term structure which two authors developed a model for predicting terms of government? which of the following models can be used to model a term structure for government who developed a r model for non stationary data who proposed a non stationary model that is based on data? what model is used to predict government
