This paper addresses the problem of estimating the population mean at the current occasion in two occasion successive sampling when non-response occurs on the current (second) occasions. Using the power transformation we have suggested classes of estimators of current population mean and their properties are studied. Optimum replacement strategies for the proposed estimators have been given and empirical studies are carried out to assess the performance of estimators. We have made suitable recommendation to the practitioners on the basis of the empirical study.

the various approaches proposed for judging the necessity of
partitioning reference values, nested analysis of variance
(ANOVA) is the likely method of choice owing to its ability
to handle multiple groups and being able to adjust for mul-
tiple factors. Box-Cox powertransformation often has been
used to transform data to a Gaussian distribution for para-
metric computation of RIs. However, this transformation
occasionally fails. Therefore, the non-parametric method

Nevertheless, we apply simple methods for reference interval estimation to generally demonstrate the usefulness of our approach but without the intention to discuss and evaluate different methods for reference interval estimation once the data have been transformed properly.

To overcome the problem of the unknown proportion of abnormal results, a common suggestion is to apply a powertransformation of the form x ′= k · x λ (with x ′=log( x
has overcome both problems by the normalization of the distributions through powertransformation and by a weighted summation of deltas based on biological variability. It also features exclusion of influential data points in deriving biological variability using an iterative procedure  and uniform expression of all test results by z-score. This method was designated as the weighted cumulative delta-check (wCDC) method. In this report, we describe the theoretical formulation and demonstrate the performance of the wCDC method with a simulation generating

accordance with the Holland hypothesis, whereas for Germany and the Netherlands
we find the opposite in support of the Cukierman–Meltzer hypothesis. In a sensitivity
analysis we show that an arbitrary choice of the heteroscedasticity parameter
influences this relationship significantly.

In the present paper, we introduce a new form of generalized Rayleigh distribution called the Alpha Power generalized Rayleigh (APGR) distribution by following the idea of extension of the distribution families with the Alpha Power transformation. The introduced distribution has the more general form than both the Rayleigh and generalized Rayleigh distributions and provides a better fit than the Rayleigh and generalized Rayleigh distributions for more various forms of the data sets. In the paper, we also obtain explicit forms of some important statistical characteristics of the APGR distribution such as hazard function, survival function, mode, moments, characteristic function, Shannon and Rényi entropies, stress-strength probability, Lorenz and Bonferroni curves and order statistics. The statistical inference problem for the APGR distribution is investigated by using the maximum likelihood and least-square methods. The estimation performances of the obtained estimators are compared based on the bias and mean square error criteria by a conducted Monte-Carlo simulation on small, moderate and large sample sizes. Finally, a real data analysis is given to show how the proposed model works in practice.
evidence that indicates it is too severe for data at large values; see Speed (2003). Other authors, such as van den Berg et al. (2006), have emphasized the need of using powertransformations other than the logarithmic transformation. One of the most widely known powertransformations is the Box-Cox transformation; see Box and Cox (1964). Thus, it is possible to introduce a family of transformations that considers the glog and power functions, in short gpower, in an analogous manner as the family of Box-Cox powertransformations works.
