The standard error of the Pearson skew [PDF]

Tutorials in Quantitative Methods for Psychology, 2015
The Pearson skew is a measure of asymmetry of a distribution, based on the difference between the mean and the median of a distribution. Here we show how to calculate the Pearson skew, estimate its standard error and the confidence interval.

Evaluation of three tractor-guidance methods for parallel swathing at two field speeds [PDF]

, 2007
This study compared the accuracy (mean error and rms error) and precision (standard deviation of error) of three tractor-guidance methods (foam-marker, light-bar, and assisted-steering systems) at two field speeds (5.6 – and 11.5 km/h) for parallel ...

Estimation of Standard Error, Linking Error, and Total Error for Robust and Nonrobust Linking Methods in the Two-Parameter Logistic Model

Stats
The two-parameter logistic (2PL) item response theory model is a statistical model for analyzing multivariate binary data. In this article, two groups are brought onto a common metric using the 2PL model using linking methods. The linking methods of mean–

Standard errors: A review and evaluation of standard error estimators using Monte Carlo simulations [PDF]

Tutorials in Quantitative Methods for Psychology, 2014
Characteristics of a population are often unknown. To estimate such characteristics, random sampling must be used. Sampling is the process by which a subgroup of a population is examined in order to infer the values of the population'

Moral Error Theory and the Belief Problem [PDF]

, 2013
Moral error theories claim that (i) moral utterances express moral beliefs, that (ii) moral beliefs ascribe moral properties, and that (iii) moral properties are not instantiated.

Evaluation of local and global atrophy measurement techniques with simulated Alzheimer's disease data [PDF]

, 2007
The main goal of this work was to evaluate several well-known methods which provide global (BSI and SIENA) or local (Jacobian integration) estimates of atrophy in brain structures using Magnetic Resonance images.

Estimation of standard error of the parameter of change using simulations [PDF]

Revista Română de Statistică, 2015
The main objective of this paper is to present the procedure for estimating standard error of parameter of change (index) of turnover in R software (R core team, 2014) when samples are coordinated.
