Red and yellow creates orange. Yellow and blue creates green. The secondary colors can be mixed further to create additional shades. Tertiary colors are the result of a primary and secondary color mixed together. For example, orange mixed with red creates red-orange.
Outliers And Influential Points. An outlier is a data point that diverges from an overall pattern in a sample. An outlier has a large residual (the distance between the predicted value () and the observed value (y)). Outliers lower the significance of the fit of a statistical model because they do not coincide with the model's prediction.
Inspection of Figure 1 revealsthat the case labeled 3 is an outlier, but it isnot influential because, being outweighedby points at neighboring values, it cannot havemuch effect on the values of the estimatedcoefficients of the model. The case labeled 1,in contrast, is an outlier on x and is an in-fluential point.
