“…Recently, in [13], the authors generalize this approach to models defined as X i = b θ 0 (X i−1 )+η i , where b θ 0 is the regression function assumed to be known up to θ 0 and for homoscedastic innovations η i . Also, in [21] and [23], the authors propose a consistent estimator for parametric models assuming knowledge of the stationary density f θ 0 up to the unknown parameters θ 0 for the construction of the estimator. For many processes, this density has no analytic expression, and even in some cases where it is known, it may be more complex to apply deconvolution techniques using this density rather than the transition density.…”
