Using this formula, you can determine whether the three points are collinear. If theareaof the triangle is zero, then the points are considered collinear. Let us say we want to calculate if A (0,-1), B(4,2), and C(8,5) are collinear points. When we substitute the coordinates in ...

Mahalanobis distance is quite effective at finding outliers for multivariate data. If there arelinear relationshipsbetween variables, Mahalanobis distance can figure out which observations break down the linearity. Unlike the other example, in order to find the outliers we need to find distance between ...
the probability of finding shared IBD segments decreases as we expand the relationship further in anindividual's family relationship chart. Kevin Donnelly proposed a mathematical model showing the theoretical probabilities of detectable DNA segments in genealogical relationships. The empirical formula to calc...
This status describes a uniform structure of the GCSN at medium-range and long-range distances, which may relate to a more linear than hierarchical structure and provide an aspect of the linear relationships empirically observed between global maritime trade and the economic size of its hinterland7...
Fetal weight was estimated from head circumference, abdominal circumference, and femur length using Hadlock’s formula [24]. Fetal weight measures at gestational weeks 10–40 were estimated from the five measurements using a linear mixed model with a cubic spline mean structure and a cubic ...
Mathematical Relationships Each of the previously described techniques has common attributes. Mathematically, the techniques are similar in effect. The Mahalanobis distance function has two important properties: (1) the diagonal cells of the S−1 represent variances, and hence “scale” the individual...

A Linear Programming Approach A commonly used metric in the separation of two locations is the distance d(ni, nj) = [(xi − xj)α + (yi, yj)α]1/α;α > 0, where (xi, yi) denotes the coordinates of point nj. This generalized distance is known in the literature as the Minkow...
In addition, there is a clear focus on the factors investigated, which concentrate in particular on the values of the energy density formula (Eq. 2.2) [50,58,110,147]. In most cases, therefore, the laser power, the hatch distance, the scanning speed, and the layer thickness or the ...
