Binary repeated measures data are commonly encountered in both experimental and observational veterinary studies. Among the wide range of statistical methods and software applicable to such data one major distinction is between marginal and random effects procedures. The objective of the study was to ...
Methods In this paper simulation studies are used to assess the effect of varying sample size at both the individual and group level on the accuracy of the estimates of the parameters and variance components of multilevel logistic regression models. In addition, the influence of prevalence of the...
State-level policy evaluations commonly use a difference-in-differences (DID) study design; yet within this framework, statistical model specification varies notably across studies. More guidance is needed about which set of statistical models perform best when estimating how state-level policies affect...

The simulation structure is described by a computing tree and realized by a wave algorithm. It is shown how to compute a variance of simulation results and to optimize it. Implementation of the discussed approach in reliability studies is provided....
Complementary log-log regression for the estimation of covariate-adjusted prevalence ratios in the analysis of data from cross-sectional studies. We assessed complementary log-log (CLL) regression as an alternative statistical model for estimating multivariable-adjusted prevalence ratios (PR) and the......
For example, powsimR was originally designed as a power analysis tool for differential expression analysis but was included as a simulation tool by a number of simulation studies9,10 in their performance comparison with other simulation methods. Being a power analysis tool, its primary usage is ...
Also, a validation method is proposed on the basis of statistical tests on metamodels fitted to the observed and simulated data. A case study illustrates the applicability of the various methods. 展开 关键词: Calibration Case studies Metamodels Statistical analysis Traffic models Traffic simulation ...

Currently, the studies of flow behavior in nanopores by MDS mainly focus on adsorption, diffusion and transport [137–139]. The typical simulation details include the long-range electrostatic force obtained by coulomb potential and PPPM methods [120,140], and the short-range interaction from the...
