Abstract |
|
|
| The stratification technique which results in minimum possible variance is called optimum stratification. The main objective of stratification is to give a better cross-section of the population so as to gain a higher degree of relative precision. The strata may be constructed either on the basis of study variable itself or by using some other variable(s) closely related with study variable known as auxiliary variable. Over the past many years several computational methods have been developed to obtain stratification points. This paper reviews the contribution toward obtaining optimum strata boundaries using mathematical programming. For several methods the comparative study has been made. |
