Chan Karolyi Longstaff Sanders JOF 1992
The following is a replication of the estimation of various interest rate models by GMM from Chan, Karolyi, Longstaff and Sanders(1992), "An Empirical Comparison of Models of the Short-Term Interest Rate", Journal of Finance, vol 47, no 3, 1209-1227. Note that the model, while estimated by monthly data, uses a parameterization which annualizes the rates. This includes two versions for the estimation; one which uses the weighting scheme from the original paper, the other uses a common weighting scheme computing under the just-identified specification.
