Graphing residuals
WebA residual plot is a graph of the data’s independent variable values ( x) and the corresponding residual values. When a regression line (or curve) fits the data well, the residual plot has a relatively equal amount of points above … WebApr 19, 2016 · Part of R Language Collective Collective. 16.

WebDisplay the residuals versus the fitted values. Residuals versus order Display the residuals versus the order of the data. The row number for each data point is shown on the x-axis. Four in one: Display all four residual plots together in one graph. Residuals versus the variables Enter one or more variables to plot versus the residuals. 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.

The graph shows a near equal number of points above the line and below the line, and the graph shows no pattern. The regression equation appears to be a good fit. NOTE: The graphing calculator will also produce a residuals plot.
