✎ ✍ 5.2 ✌ Cramer’s Rule Introduction Cramer’s rule is a method for solving linear simultaneous equations. It makes use of determinants and so a knowledge of these is necessary before proceeding. 1. Cramer’s Rule - two equations If we are given a pair of simultaneous equations a1 x + b1 y = d1 a2 x + b2 y = d2 then x‚ and y can be found from d1 b1 d2 b2 a1 b1 a2 b2 a1 d1 a2 d2 a1 b 1 a2 b 2 x= y= Example Solve the equations 3x + 4y = −14 −2x − 3y = 11 Solution Using Cramer’s

the parameters of an equation is called parameter estimation. REGRESSION ANALYSIS Although there are several techniques for estimating parameters‚ the values of the parameters are often obtained by using a technique called regression analysis. Regression analysis uses data on economic variables to determine a mathematical equation that describes the relation between the economic variables. Regression analysis involves both: 1. the estimation of parameter values
