This paper focuses on the estimation of parameters of an Erlang density using known Coefficients of variation and Kurtosis of the population basing on past experience and a simple random sample of size n from the population. Estimators using Searle D.T approach are proposed and their bias B(T) and mean squared error M(T) are calculated. The relative efficiency of T over conventional estimator x is also tabulated for various sample sizes and various C.V values, Kurtosis values. The proposed estimators are observed to be more efficient than x under the conditions established. Subject Classification: AMS 62J13.
