Usually, the presence of an outlier indicates some sort of problem. This can be a case which does not fit the model under study, or an error in measurement. Outliers are often easy to spot in histograms. For example, the point on the far left in the above figure is an outlier. A convenient definition of a outlier is a point which falls more than 1.5 times the interquartile range above the third quartile or below the first quartile. Outliers can also occur when comparing relationships between two sets of data.
To illustrate these aims, we will take two sets of data. In the first case, transformations of the variables and deletion of. outliers allow a reasonable fit. In the second case, the error function can be taken to be a gamma function.
