We consider a discrete time deterministic chaotic dynamical system, x n+1 = τ(xn), where τ is a nonlinear map of the unit interval into itself. We assume that T is piecewise expanding and piecewise C2. The effects of noise contamination are modeled by x n+1 = τ(xn) + ξn, where ξn is an independent random variable with small noise amplitude. A new statistical method is presented for filtering τ and estimating the metric entropy of τ from observed noisy data.
