Aim Apply methods of damped trend analysis to forecast inpatient glycemic control. Method Observed and calculated point-of-care blood glucose data trends were determined over 62 weeks. Mean absolute percent error was used to calculate differences between observed and forecasted values. Comparisons were drawn between model results and linear regression forecasting. Results The forecasted mea...

In this paper, we study filtering of multiscale dynamical systems with model error arising from limitations in resolving the smaller scale processes. In particular, the analysis assumes the availability of continuous-time noisy observations of all components of the slow variables. Mathematically, this paper presents new results on higher order asymptotic expansion of the first two moments of a ...

The contrast gloss and the average roughness were measured for four commercial composite filling materials. Using a factorial design, each material was subjected to four available finishing methods. A significant difference was found in the contrast gloss among finishing methods, and a significant linear regression is given which relates the inverse of the contrast gloss to the average roughnes...

Let the mixed linear regression model when mean value parameters satisfy some linear constraints be under consideration. To detect rough errors or mistakes (outliers) in observations needs a knowledge of a covariance matrix of an observation vector. If unknown variance components occur in it, some problems arise how to recognize, whether estimates or approximations of them can be used instead o...

Background: It has been shown that there is a partial correlation between blood lead level (BLL) of infants and their mothers. This study was designed to evaluate the BLL of exclusively breast-fed infants less than 6 months of age and their mothers. Methods: This was a cross-sectional study on infants below 6 months of age and their mothers who were referred to Mashhad Imam Reza Hospital, Iran...
