The equation log Q = -c log P + d is a simple linear relationship between log Q and log P. Thus, if we base our work on a regression of log(quantity) on log(price), then we can claim that the resulting …

Below, we'll look at some of the formulas associated with this simple linear regression method. In this course, you will be responsible for computing predicted values and residuals by hand.

In the equation for a line, Y = the vertical value. M = slope (rise/run). X = the horizontal value. B = the value of Y when X = 0 (i.e., y-intercept). So, if the slope is 3, then as X increases by 1, Y increases …

The calculation for the intercept is as follows: b₀ = ȳ - b₁x̄, where each term was described above. The following show formulas for building a linear regression analysis equation. β₀ (intercept): The …
