On Optimum Stratification

چکیده
In this manuscript, we discuss the problem of determining the optimum stratification of a study (or main) variable based on the auxiliary variable that follows a uniform distribution. If the stratification of survey variable is made using the auxiliary variable it may lead to substantial gains in precision of the estimates. This problem is formulated as a Nonlinear Programming Problem (NLPP), which turn out to multistage decision problem and is solved using dynamic programming technique. Keywords—Auxiliary variable, Dynamic programming technique, Nonlinear programming problem, Optimum stratification, Uniform distribution.

The Effect of Gibberellic Acid and Stratification on Germination of Alstroemeria (Alstroemeria ligtu hybrid) Seed In Vitro and In Vivo Conditions
The dormancy characteristics and optimum conditions for seed germination of Alstroemeria ligtu had not been explained. In vitro and in vivo alstroemeria (A. ligtu hybrid) seed germination tests were conducted in a Randomized Completely Design at two different treatments (gibberellic acid (GA3) 0, 100, 200 and 400 mg/l with and without stratification in 5±1oC) in four replications. Seeds were pl...
متن کاملOptimization of the PCM-integrated solar domestic hot water system under different thermal stratification conditions
Many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. Several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (ASF) of such systems. In this paper, the behaviour of integrating the phase change material (PCM) in SDHW systems is modelled and optimized n...

Seed priming with chemical, nutrient elements or pre-chilling techniques are the most effective methods to impro...
متن کاملOptimum Stratification of a Skewed Population
The focus of this paper is to develop a technique of solving a combined problem of determining Optimum Strata Boundaries (OSB) and Optimum Sample Size (OSS) of each stratum, when the population under study is skewed and the study variable has a Pareto frequency distribution. The problem of determining the OSB is formulated as a Mathematical Programming Problem (MPP) which is then solved by dyna...
