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.
Only the point at x=90 is therefore caught as an outlier, even though the point at x=52 is clearly also an outlier. This occurs because the statistics of centre and distanceâthe mean and standard deviation, respectivelyâthat we're using to spot outliersâ¦ are themselves strongly affected by outliers.
