Figure 2.20. The rankit plot G15 (the normal probability plot, x-axis: the standardised normal quantile uPi, y-axis: the order statistic x(i) for samples with (a) norm, symmetric (Gaussian, normal), and (b) log, asymmetric (log.-normal) distributions, QC-EXPERT. ...
With symmetric data, the distribution is bell-shaped and somewhat symmetric. In the boxplot, we see that Q1 and Q3 are approximately equidistant from the median, as are the minimum and maximum values. Also, both whiskers (lines extending from the boxes) are approxim...

Due to the symmetry properties of the shear stresses, the stress tensor is symmetric and thus has six independent components. Rotating the cube in Fig. 2.1 would, in general, change the values of normal and shear stresses (except in the case of a uniform, so-called hydrostatic compression or...
Along with advances in technology, matrix data, such as medical/industrial images, have emerged in many practical fields. These data usually have high dimensions and are not easy to cluster due to their intrinsic correlated structure among rows and colum
This approach is implemented and applied to the calculation of the 𝐾−𝐿𝐿 Auger and autoionization spectra of ozone, which is a 𝐶2𝑣 symmetric molecule, whose importance in our atmosphere to filter out radiation has been widely confirmed. We also show the effect that the molecular...
The curve is symmetric at the center (i.e. around the mean, μ). Exactly half of the values are to the left of center and exactly half the values are to the right. The total area under the curve is 1, or 100%. In other words, the curve represents 100% of all possible data. ...
Note that the log-normal distribution is not symmetric, but is skewed to the right. If you have data that is skewed to the right that fits the log-normal distribution, you may be able to access various tests described elsewhere on this website that require data to be normally distributed....
