Sequential procedures are adopted based on the maximum likelihood estimators (MLE) and uniform minimum variance unbiased estimators (UMVUE) of the scale parameter. A comparative study of the two sequential procedures is done and second-order approximations are obtained and they are proved to be 'asymptotically efficient and consistent.'

Due to the sensitivity of characters, practitioners don't get the actual response. Randomized response technique (RRT) models are developed to reduce the bias raised by an evasive response on the sensitive variable. The measurement error (ME) is usually always present in the surveys so we need to study the RRT models with ME. We propose an estimator to predict the population mean of a sensitive variable in the influence of ME. The properties of the proposed estimator are studied and comparisons are made with the existing estimators. At last, a simulation study is executed to illustrate the results numerically.

In order to fulfill this aim, it is important to collect and use the data carefully and minimize the possibility of various types of errors. Nonresponse (NR) and measurement error (ME) are the two major types of nonsampling error that occur in almost every survey. We propose an estimator of the population mean and study its efficacy in the combined and separate effects of NR and ME. Some existing estimators are also considered for comparison. A simulation study was performed to see its efficiency numerically.
