About
The regression application plots the price of one product against another, with the points plotted being the respective prices of each product at each point in time in the duration selected.
Regression analysis can be used to study whether the movements of two products are correlated (ie. if they tend to move together or in opposite directions), and measure how responsive the change in price of one product is relative to the other. The line of best fit equation as well as the strength of correlation (both R-squared and adjusted R-squared) are displayed.
(Density of data points is also shown as bar charts along the axes.)
