Heterogeneity of Error Variances in a Randomized Block Design

Comparing Variances of Several Measurement Methods Using a Randomized Block Design with Repeat Measurements: A Case Study

In this paper we consider the problem of comparing variances of several measurement methods in a randomized block design with repeat measurement methods. The analysis is presented in the context of an actual consulting study, which motivated this paper. We demonstrate how in a practical data analysis, a combination of informal graphical methods and formal inferential methods (multiple compariso...

Problems of Usual Weighted Analysis of Variance (wanova) in Randomized Block Design (rbd) with More than One Observations per Cell When Error Variances Vary from Cell to Cell

Simple heteroscedasticity is discussed in detail by Sen (1984), Sen & Ponnuswamy (1991) and Rahaman and Sen (1995). In this paper, heteroscedasticity is considered in a RBD assuming error variances vary from cell to cell. There are more than one observations per cell in this layout. The twoway general heteroscedastic model is considered here with interaction. On the assumption that the unequal ...

Randomized Block Design

Example It is common in nutrition studies to compare diets by feeding them to newly weaned male rats and measuring the weight gained by the rats over a 28-day period. The initial weight of the rats is an extraneous factor that is especially important as an influence on weight gain. Rather than randomly assign 10 rats to each diet, we first divide the animals into 10 groups of 3 rats each based ...

investigating the integration of translation technologies into translation programs in iranian universities: basis for a syllabus design in translation technology

today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
