Expert Solution

Step 1

Linear regression: Suppose (x₁, y₁), (x₂, y₂)---(x_n, y_n) are n pairs of observations on variables X and Y.

we assume that Y a dependent variable, which can be expressed in terms of x. The simplest form is the linear relation. Suppose y = β0+β1X. however, when we observe the numerical values of x and y the relation may not be observed perfectly. we assume the model.

y = β₀+β₁X+ε

y = Response variable,

x = Explanatory variable.

β₀ and β₁ are constants.

ε error component.
