BACKGROUND Neck circumference (NC) is an anthropometric measure of obesity for upper subcutaneous adipose tissue distribution which is associated with cardiometabolic risk. This study investigated whether NC is associated with indicators of chronic kidney disease (CKD) for high cardiometabolic risk patients. METHODS A total of 177 consecutive patients who underwent the outpatient departments ...
The quotient correlation is defined here as an alternative to Pearson’s correlation that is more intuitive and flexible in cases where the tail behavior of data is important. It measures nonlinear dependence where the regular correlation coefficient is generally not applicable. One of its most useful features is a test statistic that has high power when testing nonlinear dependence in cases whe...

The purpose of this document is to summarize Part I of the book “Time Series Analysis by State Space Methods ”, written by James Durbin and Siem Jan Koopman.
Food production in Nigeria has not matched with the rate of population growth leading to reduction national food independence and self-reliance. As a result, is facing serious insecurity. Therefore, this research examined impacts climate change on security Nigeria. Annual time-series (proxy index), annual rainfall, temperature, rate, urban agricultural land used from 1980 2019 were used. The Au...
Service systems such as call centers and hospital emergency rooms typically have strongly time-varying arrival rates. Thus, a nonhomogeneous Poisson process (NHPP) is a natural model for the arrival process in a queueing model for performance analysis. Nevertheless, it is important to perform statistical tests with service system data to confirm that an NHPP is actually appropriate, as emphasiz...
An Encompassing Approach to Conditional Mean Tests with Applications to Testing Nonnested Hypotheses
A general class of tests designed to detect conditional mean misspecification for cross section or time series applications is proposed. The tests are derived from a particular application of the encompassing principle. The resulting conditional mean encompassing (CME) tests contain as special cases a version of the Lagrange Multiplier test for nested models, a new test in the presence of nonne...
