PURPOSE:To greatly simplify the arithmetic, by minimizing the total sum of the squares of the difference between the measured value of function and the measured value of a spot concurrence formed by shifting the measured value of function on an axis (u). CONSTITUTION:When the function (v) of...
Objective To explore the solution to second-order variation coefficient linear differential equations.Methods By constructing the models of the solution to this kind of equation,the concept of all levels of derivative equations is obtained.Results The existence of the derivative equations,and the recurre...

Legendre's equation: (17.17)(1−x2)d2ydx2−2xdydx+n(n+1)y=0 In certain other cases an equation with variable coefficients can be converted into one with constant coefficients by means of a change of variable. In general, however, solutions of linear differential equations with variable...
Gini’s coefficient defined under the formalism of a fraud-scoring framework given in Equation 9 is equivalent to the expression derived for the revenue inequality in Equation 2, under the assumption that the credit score variable stands in place of the revenue variable. Proof From Equation 3 it...
Noun1.regression coefficient- when the regression line is linear (y = ax + b) the regression coefficient is the constant (a) that represents the rate of change of one variable (y) as a function of changes in the other (x); it is the slope of the regression line ...
