in a subclass of the scale-parameter exponential family, we consider the sequential pointestimation of a function of the scale parameter under the loss function given as the sum of the weightedsquared error loss and a linear cost. for a fully sequential sampling scheme, second order expansions areobtained for the expected sample size as well as for the regret of the procedure. the former resear...

this article aims to provide a simple robust method to test the parameters of a normal population by using the new diagnostic tool called the “forward search” (fs) method. the most commonly used procedures to test the mean and variance of a normal distribution are student’s t test and chi-square test, respectively. these tests suffer from the presence of outliers. we introduce the fs version of...

Multiple response categorical variables (MRCVs), also known as “pick any” or “choose all that apply” variables, summarize survey questions for which respondents are allowed to select more than one category response option. Traditional methods for analyzing the association between categorical variables are not appropriate with MRCVs due to the within-subject dependence among responses. We have d...

This paper proposes a new method of improved meta analysis to combine relative risk for both homogeneous and heterogeneous set of studies. The standard meta analyses don’t give any conclusive result when the effects of heterogenous studies are combined. The proposed improved meta analysis uses the predicted relative risk, and chi-square test to check the heterogeneity of the effects. Confidence...

The study examines the influence of demographic variables age, gender, marital status, educational level, occupation, monthly income and type of account held by the clients in non metro cities of Tamil Nadu, India. The paper builds on existing literature in demographic variables towards acceptance of internet banking. Quantitative analysis was carried out by collecting response through a well d...

Applied researchers have employed chi-square tests for more than one hundred years. This paper addresses the question of how one should follow a statistically significant chi-square test result in order to determine the source of that result. Four approaches were evaluated: calculating residuals, comparing cells, ransacking, and partitioning. Data from two recent journal articles were used to i...

An epidemiological study was conducted at Pet centre, University of Veterinary and Animal Sciences Lahore for the prevalence of Babesiosis in cats. A total of (n=5,183) cats, during the year January 2007 to December 2009 were examined. The monthly prevalence of Babesiosis and distribution by age breed and gender were calculated by chi square test for comparison. The overall prevalence was 163 (...
