WebbTECHNIQUE #9: Regression Analysis. OVERVIEW: The premise is that changes in the value of a main variable (for example, the sales of Product A) are closely associated with changes in some other variable(s) (for example, the cost of Product B).So, if future values of these other variables (cost of Product B) can be estimated, it can be used to forecast … WebbExample of simple linear regression When implementing simple linear regression, you typically start with a given set of input-output (𝑥-𝑦) pairs. These pairs are your observations, shown as green circles in the figure. For example, the leftmost observation has the input 𝑥 = 5 and the actual output, or response, 𝑦 = 5.
