Case Study Regression equation
Using the equation ( With Numbers ) ,Provide a simple example by substituting in the equation ( once ) and then explain the effect on demand of a particular product ( Cars )
No Need for long, details calculations. just a simple definition for each variable and it’s effect ( only 1 Page )
Regression equation: linear, additive
eg: Y = a + b1X1 + b2X2 + b3X3 + b4X4
Y: dependent variable
a: constant value, y-intercept
Xn: independent variables, used to explain Y
bn: regression coefficients (measure impact of independent variables)
