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.
Therefore, it is important. to be able to detect outliers and influential. points. There is a distinction between the two. because a point that is an outlier (either on y. or in the space of the predictors) will not nec-. essarily be influential in affecting the regression. equation. Examples are given later to illustrate. this concept.
