The binomial coefficient is the number of ways of picking unordered outcomes from possibilities, also known as a combination or combinatorial number. The symbols and are used to denote a binomial coefficient, and are sometimes read as " choose ." therefore gives the number of k -subsets possible out of a set of distinct items.

Calculating the Gini Coefficient. Once a Lorenz curve is constructed, calculating the Gini coefficient is pretty straightforward. The Gini coefficient is equal to A/ (A+B), where A and B are as labeled in the diagram above. (Sometimes the Gini coefficient is represented as a percentage or an index, in which case it would be equal to (A/ (A+B.

The Matthews correlation coefficient is just a particular application of the Pearson correlation coefficient to a confusion table. A contingency table is just a summary of underlying data. You can convert it back from the counts shown in the contingency table to one row per observations.

The formula for calculating price elasticity is as following; Ep= % change in quantity demanded (Q) / % change in price (P) Example: Price Elasticity Where Ep represents elasticity coefficient, %Q shows change in quantity demanded, and %P represents change in price of particular goods and services.

By extension, the Pearson Correlation evaluates whether there is statistical evidence for a linear relationship among the same pairs of variables in the population, represented by a population correlation coefficient, ρ (“rho”). The Pearson Correlation is a parametric measure. This measure is also known as: Pearson’s correlation

The definition of viscosity is as follows: Viscosity is a measure of a fluid’s resistance to flow. The SI unit of viscosity is poiseiulle (PI). Its other units are newton-second per square metre (N s m-2) or pascal-second (Pa s.) The dimensional formula of viscosity is [ML-1 T-1].

The Pearson correlation coefficient (r) is the most common way of measuring a linear.

The dimensions of dynamic viscosity are force × time ÷ area. The unit of viscosity, accordingly, is newton -second per square metre, which is usually expressed as pascal -second in SI units. The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature.

The drag equation may be derived to within a multiplicative constant by the method of dimensional analysis. If a moving fluid meets an object, it exerts a force on the object. Suppose that the fluid is a liquid, and the variables involved – under some conditions – are the: speed u, fluid density ρ, kinematic viscosity ν of the fluid,

Unit of Coefficient of Viscosity. The centimetre-gram-second or CGS unit of coefficient of viscosity, η is . dyne-sec/ cm 2 which is equal to Poise. Where one poise is exactly 0.1 Pa·s. The meter-kilogram-second or MKS unit is: Kilogram per meter per second or. Kg m-1 s-1. Coefficient of Viscosity Unit and Dimension. Since, the formula for.

Important Points: The Silhouette coefficient of +1 indicates that the sample is far away from the neighboring clusters. The Silhouette coefficient of 0 indicates that the sample is on or very close to the decision boundary between two neighboring clusters.
