This paper presents new results on the properties of indirect nonparametric estimation using
closed-loop data. Specific results developed include finite sample bias and variance. We
show that previous asymptotic results hold only when the signal-to-noise ratio is large. We
develop an expression which holds generally and which departs significantly from the
known asymptotic results. Simulations are presented which substantiate the validity of the
general expression.
