  • Fine-Tuning Some Resistant Rules for Outlier Labeling

    David C Hoaglin, Boris IglewiczARTICLEJournal of the American…1987

    A previous study examined the performance of a standard rule from Exploratory Data Analysis, which uses the sample fourths, FL and FU , and labels as “outside” any observations below FL – k(FU – FL ) or above FU + k(FU – FL ), customarily with k = 1.5. In terms of the order statistics X (1) ≤ X (2) ≤ X (n) the standard definition of the fourths is FL = X(f) and FU = X (n + 1 − f), where f = 1⁄2[(n + 3)/2] and [·] denotes the greatest-integer func…

  • Performance of Some Resistant Rules for Outlier Labeling

    David C Hoaglin, Boris Iglewicz et al.ARTICLEJournal of the American…1986

    The techniques of exploratory data analysis include a resistant rule for identifying possible outliers in univariate data. Using the lower and upper fourths, FL and FU (approximate quartiles), it labels as “outside” any observations below FL − 1.5(FU — FL ) or above FU + 1.5(FU — FL ). For example, in the ordered sample −5, −2, 0, 1, 8, FL = −2 and FU = 1, so any observation below −6.5 or above 5.5 is outside. Thus the rule labels 8 as outside. S…
