Standard error estimation by an automated blocking method

An Automated Method for Serum Magnesium Estimation.

An automated method for magnesium determination in serum is described using conventional AutoAnalyser equipment. The method gives results comparable with those obtained by the flame photometer. The method may prove particularly useful with subnormal serum magnesium levels.

SIMEX and standard error estimation in semiparametric measurement error models.

SIMEX is a general-purpose technique for measurement error correction. There is a substantial literature on the application and theory of SIMEX for purely parametric problems, as well as for purely non-parametric regression problems, but there is neither application nor theory for semiparametric problems. Motivated by an example involving radiation dosimetry, we develop the basic theory for SIM...

An Opertional Method for The Numerical Solution of Two Dimensional Linear Fredholm Integral Equations With an Error Estimation

Automated Estimation of Vector Error Correction Models

Model selection and associated issues of post-model selection inference present well known challenges in empirical econometric research. These modeling issues are manifest in all applied work but they are particularly acute in multivariate time series settings such as cointegrated systems where multiple interconnected decisions can materially a¤ect the form of the model and its interpretation. ...

Standard error as standard?

To the Editor: I am concerned about errors in simple statistical concepts in articles recently published in Circulation. First, I worry about the widespread use of the standard error of mean (SEM) to describe the variability of numerical data. Specifically, SEM was used in 30% of the clinical investigations and reports and in 76% of the basic science reports analyzed for this purpose (the first...
