Effect of Non-Normality on Sampling Plan Using Yule’s Model

In this paper, the effect of non-normality on sampling plan using Yule’s model (second order auto regressive model {AR (2)}) represented by the Edgeworth series is studied for known $sigma$. The effect of using the normal theory sampling plan in a non-normal situation using Yule’s model is studied by obtaining the distorted errors of the first and second kind. As one will be interested in having a suitable sampling plan under Yule’s model for non-normal variables the values of n and k are determined.
