The squared multiple correlation coefficient has been widely employed to assess the goodness-of-fit of linear regression models in many applications. Although there are numerous published sources that present inferential issues and computing algorithms for multinormal correlation models, the statistical procedure for testing substantive significance by specifying the nonzero-effect null hypothe...

A simple correlated channel model for ultrawideband (UWB) multiple-antenna systems is proposed. The authors show that a single numerical value of the spatial correlation coefficient is sufficient to accurately model the performance of UWB spatial multiplexing systems in an indoor environment. The appropriate value of the correlation coefficient is selected by ensuring a close match between the ...

Using real time student response systems (clickers) in Management Information Systems classes (as well as in other disciplines) has previously been shown to lead to better student engagement and better student performance. This paper considers how the students’ overall performance in the class correlates with the students’ performance on various assessment tools used in the class. For medium si...

BACKGROUND The increasing prevalence of diabetes in Ontario means that there will be growing demand for hemoglobin A1c (HbA1c) testing to monitor glycemic control for the management of this chronic disease. Testing HbA1c where patients receive their diabetes care may improve system efficiency if the results from point-of-care HbA1c testing are comparable to those from laboratory HbA1c measureme...

to determine the gestational age of ultrasound devices, commonly used standard tables. the aim was to determine the gestational age of pregnant women admitted to hospitals in zahedan with hadlock and osaka table and gestational age derived from the tables to be adjusted to determine the gestational age of the actual use of tables for a more accurate determination of gestational age for the prop...
