This paper introduces an easy to follow method for direct estimation of a continuous time system dynamic model. To minimise the output error a continuous time model can be estimated directly by discretisation and simulation under a nonlinear least squares algorithm. This method is applied to the estimation of a stock market model. This paper also discusses the numerical difficulties involved in discrete time models that bring about the unit root illusion in econometrics, which can be avoided by the use of continuous time models.
