We consider nonparametric stochastic volatility models in discrete time with unknown distribution of the innovations of the return process. As underlying and not observable volatility process we assume a nonparametric autoregressive structure of first order. We are interested in estimators for this autoregression function. The considered models generalise on one hand parametric autoregressive random variance models and on the other hand nonparametric stochastic volatility models for which the distribution of the innovations of the returns is assumed to be known. We make use of the well accepted assumption that volatility changes (rather) slowly. In a first model we deal with the extreme situation that at least two observed returns are based...
