5x + 3y = 7z 5, 3, and 7 are coefficients and they are integers, they are integer coefficients
In a term (or monomial), the number part is the numerical coefficient (often just called the coefficient), and the variable part (letters) is the literal coefficient. Some examples: 3x2: num coeff = 3, lit coeff = x2 -0.5xy4z9: num coeff = -0.5, lit coeff =xy4z9 17: num coeff = 17, no literal coefficient w: num coeff = 1, lit coeff = w
Static and kinetic coefficients
An algebraic number is one that is a root to a non-zero polynomial, in one variable, whose coefficients are rational numbers.Equivalently, if the polynomial is multiplied by the LCM of the coefficients, the coefficients of the polynomial will all be integers.
(a) Correlation coefficient is the geometric mean between the regression coefficients. (b) If one of the regression coefficients is greater than unity, the other must be less than unity. (c) Arithmetic mean of the regression coefficients is greater than the correlation coefficient r, provided r > 0. (d) Regression coefficients are independent of the changes of origin but not of scale.
