WebSep 13, 2024 · How to Assess Constant Variance. The most common way to determine if the residuals of a regression model have constant variance is to create a fitted values vs. residuals plot. This is a type of plot that displays the fitted values of the regression model along the x-axis and the residuals of those fitted values along the y-axis. WebThe gravity model in economics was until relatively recently an intellectual orphan, unconnected to the rich family of economic theory. This review is a tale of the orphan's reunion with its heritage and the benefits that have flowed from it. Gravity has long been one of the most successful empirical models in economics.
