2. Split normal distribution - Wikipedia

   en.wikipedia.org/wiki/Split_Normal_Distribution

   When σ 2 ≠σ 1 the constant A is different from the constant of normal distribution. However, when = = the constants are equal. The sign of its third central moment is determined by the difference (σ 2-σ 1). If this difference is positive, the distribution is skewed to the right and if negative, then it is skewed to the left.

3. Split (graph theory) - Wikipedia

   en.wikipedia.org/wiki/Split_(graph_theory)

   The quotient graph can be formed by deleting i from the tree, forming subsets of vertices in G corresponding to the leaves in each of the resulting subtrees, and collapsing each of these vertex sets into a single vertex. Every quotient graph has one of three forms: it may be a prime graph, a complete graph, or a star. [2]

   linewidths: different line widths may be defined for each series of data with csv, if set to 0 with "showSymbols" results with points graph, eg.: linewidths=1, 0, 5, 0.2; showSymbols: show symbol on data point for line graphs, if a number is provided, the symbol size (default 2.5) may be defined for each data series, eg.: showSymbols=1, 2, 3, 4

6. Squared deviations from the mean - Wikipedia

   en.wikipedia.org/wiki/Squared_deviations_from...

   In statistics, the two-way analysis of variance (ANOVA) is an extension of the one-way ANOVA that examines the influence of two different categorical independent variables on one continuous dependent variable. The two-way ANOVA not only aims at assessing the main effect of each independent variable but also if there is any interaction between them.

7. Norm (mathematics) - Wikipedia

   The concept of unit circle (the set of all vectors of norm 1) is different in different norms: for the 1-norm, the unit circle is a square oriented as a diamond; for the 2-norm (Euclidean norm), it is the well-known unit circle; while for the infinity norm, it is an axis-aligned square.

8. Partition of sums of squares - Wikipedia

   en.wikipedia.org/wiki/Partition_of_sums_of_squares

   If the sum of squares were not normalized, its value would always be larger for the sample of 100 people than for the sample of 20 people. To scale the sum of squares, we divide it by the degrees of freedom, i.e., calculate the sum of squares per degree of freedom, or variance. Standard deviation, in turn, is the square root of the variance.

9. Square number - Wikipedia

   en.wikipedia.org/wiki/Square_number

   Alternatively, the n th square number can be calculated from the previous two by doubling the (n − 1) th square, subtracting the (n − 2) th square number, and adding 2, because n 2 = 2(n − 1) 2 − (n − 2) 2 + 2. For example, 2 × 5 2 − 4 2 + 2 = 2 × 25 − 16 + 2 = 50 − 16 + 2 = 36 = 6 2. The square minus one of a number m is ...
