Ratio Estimation and Approximate Optimum Stratification in Electric Poher Surveys
= Some of the history of a monthly sales and revenue survey, and the current status of that survey and others, are given as background to changes now being implemented. Sampling will now take place at the State level, instead of the national level; more complete use will be made of auxiliary information; work has been done to control cv's for several variables simultaneously; and a test origina...
متن کاملRatio and Regression Methods of Estimation
4.1 INTRODUCTION In sampling theory the auxiliary information is being utilized in following ways: Utilization of information at pre-selection stage i.e. for stratifying the population. Utilization of information at selection stage i.e. in selecting the units with probabilities proportional to some suitable measure of size (size being based on some auxiliary variables). Utilization of inf...
متن کاملMethods for stratification of person-time and events – a prerequisite for Poisson regression and SIR estimation
INTRODUCTION Many epidemiological methods for analysing follow-up studies require the calculation of rates based on accumulating person-time and events, stratified by various factors. Managing this stratification and accumulation is often the most difficult aspect of this type of analysis. TUTORIAL We provide a tutorial on accumulating person-time and events, stratified by various factors i.e...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
On Optimum Stratification
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), w...
