WebA residual plot is a graph that is used to examine the goodness-of-fit in regression and ANOVA. Examining residual plots helps you determine whether the ordinary least squares assumptions are being met. If these assumptions are satisfied, then ordinary least squares regression will produce unbiased coefficient estimates with the minimum variance. WebResiduals for data points. In the above graph, the vertical gap between a data point and the trendline is referred to as residual. The spot the data point is pinned determines whether the residual will be positive or negative. All points above the trendline show a positive residual and points below the trendline indicate a negative residual.
