F empirical model discovery and Role Of Model role of model Hendry and Doornik outline stages of developing a viable model of a complicated evolving process They discuss the discovery stages in detail considering both the theory of model selection and the performance of several algorithms They describe extensions to tackling outliers and multiple breaks leading to the general case ofcandidate variables performance of several algorithms They describe extensions to tackling outliers and multiple breaks leading to the general case ofcandidate variables observations Finally they briefly consider selecting models specifically for forecastin. .
