求翻译：Since φ = 1, the zero of 1−φB is on the unit circle, the model thus has a unit root.This also gives the definition of a unit root. Later on we shall consider the least squares estimate of the coefficient φ for a random-walk model which is the unit-root problem commonly discussed in the literature.The random-walk model 是什么意思？ 待解决
