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.
Identification of potential outliers is important for the following reasons. 1  An outlier may indicate bad data. For example, the data may have been coded incorrectly or an experiment may not have been run correctly. 2  In some cases, it may not be possible to determine if an outlying point is bad data.
