This PhD thesis deals with predicting long-memory processes. We assume that the processes are weakly stationary, linear, causal and invertible, but only a finite subset of the past observations is available. We first present two approaches when the stochastic structure of the process is known : one is the truncation of the Wiener-Kolmogorov predictor, and the other is the projection of the forecast value on the observations, i.e. the least-squares predictor. We show that both predictors converge to the Wiener-Kolmogorov predictor. When the stochastic structure is not known, we have to estimate the coefficients of the predictors defined in the first part. For the truncated Wiener-Kolomogorov, we use a parametric approach and we plug in the f...
