The conditional expectations, E (Y (h)| Y (u),−∞< u≤ 0) and E (Y (h)| Y (u),− M≤ u≤ 0) with h> 0 and 0< M<∞ are determined for a continuous-time ARMA (CARMA) process (Y (t)) t∈ R driven by a Lévy process L with E| L (1)|<∞. If E (L (1) 2)<∞ these are the minimum mean-squared error predictors of Y (h) given (Y (t)) t≤ 0 and (Y (t))− M≤ t≤ 0 respectively. Conditions are also established under which the sample-path of L can be recovered from that of Y, both when Y is causal and strictly stationary and (without these assumptions) when L is a pure-jump Lévy process. When E (L (1) 2)<∞ and Y is causal and strictly stationary the best linear predictors P (Y (h)| Y (u), u≤ 0) and P (Y (h)| Y (− n Δ), n∈ N) are also determined, the latter yielding a simple algorithm for determining the parameters of the ARMA process obtained by sampling the CARMA process at regular intervals.
