Abstract/Description: | It is well known that ancillary information helps in obtaining efficient results in estimation of population parameter as mean etc. A number of procedures based on ancillary information have been developed but none provides control on sampling error which is a very important auspect in sampling. In this dissertation. A selection procedure has been suggested which makes use of ancillary information to ensure the selection of a representative sample. i.e. a Sample for which relative margin of error of sample estimate from population parameter by within a specified margin. Further, the probability that sample estimate for study character will also differ from population parameter by a specified margin error has been calculated. For different ranges of sample size. Correlation coefficient between study and auxiliary variables, margins of error and coefficients of variation. This probability is generally of high order and time the suggested procedure can be used satisfactorily in most of practical situations. To obtain Horwins-thompson’s estimates of mean and variance, method of calculating wj’s and wij’s for suggested procedure has also been given. In some cases wi is equal to zero or wij is equal to zero for some unit or pair of unit, the selection procedure and method of computing wi and wij for all the units have been modified. The controlled selection procedure as modification of the suggested procedure has been given and the method of obtaining wj’s and wij’s based on controlled selection has also been discussed. Some theoretical and natural populations have also been considered to compare the suggested schemes with existing procedures empirically. The suggested schemes have been found to be highly satisfactory, in all the situations. |
