      denotes an observation with a large standardized residual. X. denotes an observation whose X value gives it large influence. Residuals vs Fits for t90. Plot shows non constant variance and very unusual standardized residuals. Suggests making transformation on both x and y. We will discuss this later. Transform by taking logs of both variables.

      Residual-Skew.dat. and . Residual-Hetero.dat. ... Oh my. Notice that the residuals are not symmetrically distributed about zero. They are mostly positive with low and high values of predicted Y and mostly negative with medium values of predicted Y. If you were to find the means of the residuals at each level of Y and connect those means with ...

      A residual has no meaning since one of the variables is categorical. A study of the fuel economy for various automobiles plotted the fuel consumption (in liters of gasoline used per 100 kilometers traveled) vs. speed (in kilometers per hour). A least-squares regression line was fitted to the data and the residual plot is displayed to. The right.

      A residual is the difference between an observed value of the response variable and the value predicted by the regression line. residual = observed value of y – predicted value of y. A residual plot is a graph of the regression residuals plotted against the explanatory variable x. Residual plots help us assess the fit of a regression line.
