While random errors can be minimized by increasing sample size and averaging data, it's harder to compensate for systematic error. The best way to avoid systematic error is to be familiar with the limitations of instruments and experienced with their correct use. Random Error Examples and Causes ...
A simple scaling technique to avoid the distortion of the fitted parameters, inherent in the logarithmic transformation of the rate equation, is tested on several examples, and an iterative discarding method for the selection of accurate data points is recommended....
The homogeneity hypothesis is a common assumption in classic measurement. However, the item response theory model assumes that different respondents with same ability have the same option probabilities, which may not hold. The aim of this study is to pro
can be performed independently while boosting is performed sequentially. As opposed to bagging where variance is reduced, boosting will try to reduce bias. In addition to gradient boosting, AdaBoost (adaptive gradient boosting) and XGBoost (extreme gradient boosting) are examples of boosting algorithms...
Examples of using meta mvregress Examples are presented under the following headings: Example 1: Univariate versus multivariate meta-analysis Example 2: Random-effects multivariate meta-regression Example 3: Identical results from univariate and multivariate analyses Example 4: Heterogeneity statistics ...

Here we demonstrate how, using human keratinocytes and fibroblasts as examples. The two resulting models reflect the cells’ different roles in the organism, it seems, and show that a cell has a memory of past velocities. They also suggest how to distinguish quantitatively between various surfaces...
Some examples of II–VI semiconductor ternary alloys are Zn1−xCdxSe, Zn1−xCdxTe, Zn1−xMgxSe, ZnS1−ySey, CdS1−yTey, etc. The Zn1−xCdxSe alloy has been of significative importance because it has been used to fabricate QWs and quantum dots in the active region of LEDs ...
Numerous examples appear in the natural sciences including in ecology4–8, biochemistry9–11 and chemistry12. In addition, many human activities involve situations where a target has to be found. Some instances are the location of a lost object, rescue operations, or fugitive prosecutions13. ...
