BACKGROUND Models of hepatitis C virus (HCV) kinetics are increasingly used to estimate and to compare in vivo drug's antiviral effectiveness of new potent anti-HCV agents. Viral kinetic parameters can be estimated using non-linear mixed effect models (NLMEM). Here we aimed to evaluate the performance of this approach to precisely estimate the parameters and to evaluate the type I errors and th...
The study aims to find a long-run empirical correlation between crude prices and the Nigerian Economy. Therefore, Independent Variable for is natural log of Dependent would be economic activity in Nigeria (Operationalized using GDP). research explores Vector Autoregression Model (VAR Model), Serial Correlation LM Test, VAR Granger Causality/Block Exogeneity Wald Tests, Forecast Error Variance D...
Proportional odds models are commonly used to model ordinal responses, but the proportional assumption may not hold in practice, leading biased inference. Tests such as score, Wald and likelihood ratio (LR) have been proposed evaluate based on without assumption. Brant has an independent binary model-based Wald-type test, Wolfe Gould extended idea propose LR-type test. This paper provides a bri...
BACKGROUND The mid-term prognostic significance of ECG-gated single-photon emission computed tomography (SPECT) remains unclear in Japanese patients with type 2 diabetes mellitus (DM). In the present study rates of future cardiac events (nonfatal acute myocardial infarction (AMI), cardiac death (CD) and severe heart failure (HF) requiring hospitalization) were compared in patients with and with...
