This paper considers parameter estimation for continuous-time diffusion processes which are commonly used to model dynamics of financial securities including interestrates.To understand why the drift parameters are more difficult to estimate than the diffusion parameter as observed in previous studies,we first develop expansions for the bias and variance of parameter estimators for two mostly employed interestrate processes,Vasicek and CIR processes.
