kurtosis (from the Greek word meaning bulging) is a measure of the "peakedness
" of the probability distribution of a real-valued random variable.
The distribution of SOC contents was nearly normally distributed, but showed some positive skew (skewness = 0.26) and peakedness
near the mean (kurtosis = 0.12).
In evaluating for kurtosis, or the flatness or peakedness
of the distribution, the variables followed a mesokurtic or normal distribution.
The coefficient of kurtosis, which measures the peakedness
of a distribution, is very high for Bilecik.
Kurtosis, the flatness or peakedness
of a distribution (22), occurs along the y axis and was also evident in the raw data.
The considered GLIH-based features included variance, skewness, and kurtosis with each characterizing the shape of intensity histogram, respectively, from the aspect of dispersion, symmetry, and peakedness
. For GLCOM, with a voxel displacement of 1, the neighboring properties of the voxels in the 13 directions of 3D space were taken into account simultaneously by adding up the intensity cooccurrence patterns into one single matrix .
or flatness of the distribution of each of the variables as revealed by the Kurtosis statistic were recorded to be flat or platykurtic relative to the normal for LNFMV, and LNLEV; being less than 3.
In this reverse engineering software, procedures such as smoothing surface roughness, filling cavities, elimination of peakedness
, and revision of surface coincidences were performed, and NURBS (Non-Uniform Rational B-Splines) surfaces were obtained.
The degree of peakedness
(kurtosis) of the grains relative to the average was calculated.
The skewness addresses the symmetry of a distribution and the kurtosis provides information related to the peakedness
or alternatively the "fat tails" of a distribution .
